Estimating Seating Needs for Portable Bleachers

When purchasing portable bleachers, it’s important to estimate the right amount of seating to accommodate your audience comfortably. Here’s a simple guide to help you determine the number of bleacher seats your organization will need:

1. Determine Your Audience Size

• Estimate Total Attendance: Start by estimating the maximum number of people you expect to attend your events. Consider peak attendance at your largest events, including regular spectators, participants, and any additional guests.
• Identify Audience Segments: Break down your audience into different segments if necessary (e.g., students, parents, general public) to understand seating preferences and requirements.

2. Consider Event Frequency and Type

• Frequency of Use: If your events are frequent or high-attendance (e.g., weekly sports games), you’ll need more seating than for occasional or smaller gatherings.
• Type of Event: For events where spectators are expected to stay seated for long periods, providing extra seating for comfort is advisable.

3. Calculate Required Seating Capacity

• Bleacher Row Length: Standard portable bleachers typically offer around 10-15 seats per row. Multiply the number of rows by the number of seats per row to get the total capacity of each bleacher unit.
• Total Number of Bleacher Sets: Divide your estimated audience size by the seating capacity of one bleacher set to determine how many sets you need.
• Example: If you expect 300 people and each bleacher set accommodates 50 people, you’ll need at least 6 bleacher sets (300 ÷ 50 = 6).

4. Factor in Space and Layout

• Available Space: Measure the area where the bleachers will be placed to ensure there’s enough room for the number of sets you plan to purchase. Account for walkways, exits, and any obstacles.
• Bleacher Configuration: Consider how the bleachers will be arranged. Linear setups may require more space, while angled or tiered arrangements can maximize seating in smaller areas.

5. Plan for Future Growth

• Scalability: If you expect your audience size to grow over time, consider purchasing additional bleacher sets or opting for modular bleachers that can be expanded as needed.
• Flexibility: Choose bleachers that can be easily reconfigured or combined with other seating options to accommodate different event sizes and layouts.

By following these steps, your organization can accurately estimate the amount of seating needed for your portable bleachers, ensuring that all your attendees have a comfortable place to sit.

Portable Bleacher Sizes

Once you understand clearly how much seating you need, you can determine which ones and how many portable bleachers you need to fulfill those requirements. Your choice of bleacher size will of course depend upon the configuration of the venue(s) you’re fitting.

Portable bleachers typically come in a few different standard lengths: 7.5ft, 15ft, and 21ft.

The other aspect of the bleachers that determines seating capacity is the number of rows in the bleachers. Most portable bleachers have between two and four rows.

The smallest portable bleachers, typically 2-row, 7.5-foot long units, can accommodate around 10 to 15 people. These are ideal for small gatherings or when space is limited. On the other end of the spectrum, larger portable bleachers, such as 4-row, 21-foot long units, can seat approximately 40 to 56 people, depending on the design and spacing of the seats. These larger bleachers are well-suited for medium-sized events where more spectators need to be accommodated. The capacity of each bleacher set increases with the number of rows and the length, making it important to choose the right size based on the expected crowd size and available space.

Powder Coated Versus Non-Powder Coated

Technical Differences

• Powder Coated Bleachers:
  • Coating Process: Powder coating involves applying a dry powder made of finely ground particles of pigment and resin to the surface of the bleachers. This powder is electrostatically charged and sprayed onto the metal, which is then cured in an oven. The heat causes the powder to melt and form a smooth, durable, and uniform coating.
  • Material: The coating typically adheres to aluminum or steel, creating a protective layer that is more resilient than standard paint.
  • Finish: Powder-coated bleachers have a thicker, more even finish compared to painted or uncoated bleachers, resulting in a smoother appearance with a variety of color options.
• Non-Powder Coated Bleachers:
  • Surface Treatment: Non-powder coated bleachers may be untreated, anodized (for aluminum), or simply painted with a liquid paint. These methods do not offer the same level of uniformity or protection as powder coating.
  • Material: While aluminum and steel are still the primary materials, these surfaces might lack additional protective layers, making them more vulnerable to environmental factors.
  • Finish: Non-powder coated bleachers might have a thinner, less durable finish that can wear off more easily, especially if only painted. They also tend to have fewer color options and can look less polished over time.

Functional Differences

• Durability and Longevity:
  • Powder Coated Bleachers: The powder coating provides a robust, corrosion-resistant layer that protects the bleachers from rust, scratches, chipping, and fading. This makes powder-coated bleachers ideal for outdoor use, as they can withstand harsh weather conditions, including intense sunlight, rain, and snow, without degrading.
  • Non-Powder Coated Bleachers: Bleachers without powder coating, especially if untreated or only painted, are more susceptible to corrosion, rust, and wear over time. They may require more frequent maintenance or replacement, particularly in outdoor settings where they are exposed to the elements.
• Maintenance:
  • Powder Coated Bleachers: Require minimal maintenance due to their durable, protective coating. Cleaning typically involves simple washing with water or mild detergent, and the finish is resistant to most stains and grime buildup.
  • Non-Powder Coated Bleachers: May require more upkeep, including periodic repainting or treating to prevent rust and corrosion. They are also more likely to show signs of wear and tear, requiring more frequent attention to keep them looking and functioning well.
• Aesthetic Appeal:
  • Powder Coated Bleachers: Offer a more attractive appearance with a variety of color options that remain vibrant over time. The smooth, even finish also helps maintain a professional look, making these bleachers suitable for venues that prioritize aesthetics.
  • Non-Powder Coated Bleachers: Often have a more utilitarian look, with fewer color choices and a finish that may degrade more quickly. Over time, the appearance may become dull or uneven, particularly in high-use areas.

In summary, powder-coated portable bleachers are technically superior in terms of durability, weather resistance, and aesthetic appeal compared to their non-powder-coated counterparts. The added protection from powder coating makes these bleachers more suitable for outdoor and high-traffic environments, offering longer-lasting performance with less maintenance. Non-powder-coated bleachers, while potentially more cost-effective initially, may require more frequent maintenance and may not offer the same level of protection and visual appeal, especially in harsh environments.

Low Rise Versus Standard Portable Bleachers

Structural Differences

• Height of the Riser:
  • Low-Rise Bleachers: These bleachers have a reduced riser height between rows, typically ranging from 6 to 10 inches. This lower height results in a more gradual slope, making the transition between rows less steep.
  • Standard Bleachers: Standard bleachers have a riser height between rows that is usually around 12 to 18 inches, creating a steeper incline. This allows for a higher seating capacity within a smaller footprint, as more rows can be stacked vertically.
• Seating Capacity:
  • Low-Rise Bleachers: Due to the lower riser height, low-rise bleachers may offer fewer rows within the same vertical space compared to standard bleachers. This could reduce the overall seating capacity in some configurations.
  • Standard Bleachers: With a steeper incline, standard bleachers can accommodate more rows and thus more spectators in a compact area, maximizing seating capacity.

Functional Differences

• Accessibility and Safety:
  • Low-Rise Bleachers: The lower height between rows makes these bleachers more accessible and safer, particularly for young children, elderly spectators, or individuals with mobility issues. The gentle incline reduces the risk of trips and falls, making it easier to navigate between rows.
  • Standard Bleachers: While still safe, the steeper incline of standard bleachers may be more challenging for some spectators to navigate, especially those with limited mobility. The higher steps between rows can also make these bleachers feel less stable for some users.
• Comfort:
  • Low-Rise Bleachers: The more gradual slope of low-rise bleachers can offer a more comfortable viewing experience, as the seating arrangement feels less elevated and more connected to the action. Spectators may feel more secure, especially in the front rows.
  • Standard Bleachers: Standard bleachers provide a better viewing angle for larger crowds, especially in taller configurations, but the steeper incline might be less comfortable for some users, particularly over extended periods.
• Use Cases:
  • Low-Rise Bleachers: These are ideal for settings where accessibility, comfort, and safety are top priorities, such as elementary schools, community centers, and venues with a diverse audience. They’re also well-suited for smaller, more intimate events where a close connection to the action is desired.
  • Standard Bleachers: Standard bleachers are more commonly used in larger venues like high school stadiums, sports arenas, and other facilities where maximizing seating capacity and providing a clear view for all spectators are critical.

Aesthetic and Spatial Considerations

• Aesthetic Appeal:
  • Low-Rise Bleachers: Often perceived as more inviting and less imposing, low-rise bleachers can blend more seamlessly into certain environments, particularly in community-focused or family-friendly settings.
  • Standard Bleachers: With their taller, more imposing structure, standard bleachers can create a more traditional stadium feel, which is often desired in competitive sports environments.
• Space Utilization:
  • Low-Rise Bleachers: These bleachers require more horizontal space to accommodate the same number of seats as standard bleachers, making them more suitable for venues with ample space but lower vertical clearance.
  • Standard Bleachers: Standard bleachers are more space-efficient vertically, making them ideal for venues with limited floor space but the ability to stack rows higher.

Low-rise bleachers and standard bleachers serve different purposes, each tailored to specific needs and environments. Low-rise bleachers prioritize accessibility, safety, and comfort, making them a great choice for family-oriented events and venues. Standard bleachers, with their steeper incline and higher seating capacity, are better suited for larger, more traditional sports venues where maximizing the number of spectators and providing clear sightlines are essential.

Single Plank Versus Double Plank

The choice between single plank and double plank bleachers depends on the specific needs of the venue and the audience. Single plank bleachers offer a more cost-effective and portable solution, ideal for temporary or budget-conscious setups. In contrast, double plank bleachers provide enhanced comfort, stability, and versatility, making them a better choice for venues where extended seating and spectator comfort are priorities.

We’ll take a look at the benefits and drawbacks of each of these features: single plank versus double plank.

Single Plank Bleachers

• Design: Single plank bleachers have one plank per row, which serves as the seating surface. There is no additional plank for the back or foot support, making the structure simpler and lighter.
• Benefits:
  • Cost-Effective: Single plank bleachers are typically more affordable due to the reduced amount of material used in their construction. This makes them a budget-friendly option for organizations with limited funds.
  • Lightweight and Portable: The simpler design means these bleachers are lighter and easier to move, making them ideal for temporary setups or venues where seating needs to be frequently rearranged.
  • Space-Saving: With fewer components, single plank bleachers take up less space, both when in use and when stored. This can be advantageous in smaller venues or for events where maximizing available space is important.
• Drawbacks:
  • Less Comfortable: The lack of back or foot support can make single plank bleachers less comfortable, especially for prolonged periods of sitting. Spectators may experience fatigue more quickly without these additional support features.
  • Stability Concerns: With only one plank, there’s less surface area for seating and foot placement, which can feel less stable or secure for some users, particularly on taller bleachers.
  • Limited Usability: These bleachers may not be suitable for all audiences, especially if the event requires extended seating or if the spectators are younger children or older adults who need more support.

Double Plank Bleachers

• Design: Double plank bleachers feature two planks per row—one for seating and one for foot placement or, in some cases, for back support. This creates a more robust structure with additional comfort and stability.
• Benefits:
  • Enhanced Comfort: The extra plank provides a place for spectators to rest their feet, reducing fatigue and increasing overall comfort during longer events. In some designs, the second plank also serves as back support, further improving the seating experience.
  • Increased Stability: Double plank bleachers offer more surface area, making the seating arrangement feel more secure and stable. This is particularly beneficial for taller bleachers or when seating a larger crowd.
  • Versatility: These bleachers are more versatile and suitable for a wider range of events and audiences, including those that require extended seating or need to accommodate spectators of all ages.
• Drawbacks:
  • Higher Cost: The additional materials and construction complexity make double plank bleachers more expensive than their single plank counterparts. This might be a consideration for organizations with tighter budgets.
  • Heavier and Less Portable: The added planks increase the weight of the bleachers, making them more challenging to move and set up. This can be a disadvantage in situations where portability is a key requirement.
  • Requires More Space: Double plank bleachers take up more space both when in use and when stored. This might limit their suitability for smaller venues or areas with limited storage capacity.

Why Bleachers are Typically Made of Aluminum

Bleacher seating is typically made of aluminum rather than steel primarily because of aluminum’s superior combination of light weight, durability, and resistance to corrosion. Aluminum is significantly lighter than steel, making it much easier to transport, set up, and rearrange, which is particularly important for portable bleachers that need to be moved frequently. In addition, aluminum naturally resists rust and corrosion without the need for additional treatments, making it ideal for outdoor use where the bleachers are exposed to the elements. This low-maintenance feature ensures that aluminum bleachers remain safe and visually appealing over time with minimal upkeep.

For example, consider a 21-foot bleacher set. If made from aluminum, it might weigh around 400-500 pounds, which can be easily moved by a small team or even a couple of people using the right equipment. In contrast, a similar bleacher set made from steel could weigh upwards of 1,200-1,500 pounds, making it much more cumbersome to transport and set up. This significant difference in weight not only impacts the ease of handling but also increases the logistical costs and complexity, particularly for venues that need to frequently reconfigure their seating arrangements. As a result, aluminum is the preferred material for bleacher seating, especially when portability and ease of maintenance are key considerations.
