Bleachers

Bleachers refer to a number of bench-style seating elements, typically with two or more tiered rows of seats in a fixed or portable design. Many bleachers offer optional back and/or side guardrails for added safety.

Styles

Bleachers with Guardrails: Bleachers with guardrails are bench-style seating elements designed in rows, usually of two or more rows of seats in a tier-level assembly with guardrails along the back of the back row, and usually along the left and right sides of upper rows for safety.

Bleachers without Guardrails: Bleachers without guardrails are bench-style row seating elements in tiered levels, usually with two or more rows, featuring open ends and back. Many bleachers without guardrails accept optional guardrails for the back and sides, if desired.

Portable Bleachers: Portable bleachers are tier-style bench seating with casters or wheels in a fixed or collapsible frame that rolls for easy transport. Some portable bleacher styles will offer a tilt and roll frame design with wheels on the backside and stabilizing legs at the front.

Tip-N-Roll Bleachers: Tip-N-Roll bleachers are a select bleacher design with permanently mounted 5” casters on the back leg supports, designed to allow the bleachers to tip onto the casters, with the backside facing down, for easier moving, transporting, and storage.

2-Row Bleacher Design: A 2-row bleacher design describes bleacher seating with two rows of seats, assembled in a tiered layout with the back row set higher than the front row for comfortable audience seating. A footboard supports the feet of those seated in the back row while those in the front row can simply place feet on the floor or ground.

3-Row Bleacher Design: A 3-row bleacher design refers to tiered bench-style seating with three rows assembled at different heights within a single frame and supportive footboards for the second and third rows.

4-Row Bleacher Design: A 4-row bleacher design describes bench-style bleacher seating with four plank-like beams forming the seat rows. The seat rows are assembled in a frame with tiered or layered assembly, positioning each row slightly higher than the row in front of it, with supporting footboards for the second, third, and fourth rows.

5-Row Bleacher Design: A 5-row bleacher design has a tier-style frame with five bench-like seating rows assembled at increasing heights. Each row from the second back has a footboard to support the feet of the audience seated at that level. The first row of seats is positioned to use the floor or ground rather than a footboard.

Components

Footboards: Footboards are planks that may match or coordinate with the planks forming the seating rows in a bleacher unit, positioned to support the feet of users seated in the second or higher rows of a bleacher unit. Bleachers do not typically include a footboard for the front or bottom-most row, relying instead on the use of the floor or ground for those seated along the first row.

Guardrails: Guardrails refer to the supportive components along the back and sides of taller bleacher units, providing protection on seating rows higher than 30” to reduce falls and enhance user comfort and balance.

Hard Rubber Feet: Hard rubber feet are protective pieces composed of durable rubber designed to fit the legs of select bleachers to support placement for safe use and protect flooring from scratches and other damage associated with normal use.

Locking Brake: Locking brake describes the parking-style brake that prevents a bleacher unit from rolling or sliding when engaged. The locking brake is included on select bleacher units for added safety when the wheels or casters generally maintain floor contact.

Mounted 5” Casters: Mounted 5” casters are durable 5”-diameter caster wheels mounted permanently to the back legs of select bleacher units. The casters are mounted on the vertical leg posts, providing the ability to tilt the bleacher unit on the backside and roll for easy transport or storage.

Riser: A riser is an enhancement on select bleacher units designed to add safety to bleachers. These bleachers feature a raised support section at the back of each footboard for seat rows higher than 30” providing support to prevent slipping and improve stability while moving to a seat or exiting the seating unit.

Second Footboard: Second footboard typically refers to the use of two plank-style beams to form a side footboard for each row behind the first or bottom-most row in a bleacher unit. The design offers a wider platform for feet to support balance when moving to a seat or exiting the bleachers, and while seated.

Construction Materials

Aluminum Planking: Aluminum planking refers to the plank or beam elements comprising a bleacher unit, designed with aluminum metal and typically anodized for lasting protection.

Anodized Finish: Anodized finish typically refers to aluminum that has been treated using an electrolytic passivation treatment process that increases resistance to corrosion and other signs of wear. The anodized aluminum is thicker and more durable than standard non-anodized aluminum, with a natural oxide layer coating the metal to protect from moisture, weather, and use.

Cast Iron Fittings on Guardrails: Cast iron fittings on guardrail describe the components included with a bleacher and guardrail unit to combine the guardrail and bleacher for a finished assembled seating element. The guardrails are typically welded for permanent assembly, with cast iron metal fittings included to form the connections with the bleacher frame.

Galvanized Tubing: Galvanized tubing is typically steel tubing dipped or coated in a zinc layer for protecting from corrosion, rust, and other damage associated with exposure to the elements.

MIG Welded Guardrail Assembly: MIG welded guardrail assembly refers to the pre-assembled guardrail components that are welded by the manufacturer using a Metal Inert Gas (MIG) welding process that uses electricity to form an arc that heats the metal and forces the permanent bond.

Non-Skid Mill Finish: Non-skid mill finish refers to a finishing process used often with aluminum metal to create a textured surface that reduces slipping by offering increased traction compared to smoother finishes.

Zinc-Coated Hardware: Zinc-coated hardware generally refers to steel bolts, screws, and connecting components that have been galvanized or dipped in a molten zinc coating to protect from exposure to moisture and the elements for lasting rust-free, corrosion-free use.

Features

Bleacher Width: Bleacher width refers to the length of each row or plank, with longer widths accommodating more people. Typical bleacher width options range from 9-feet to 21-feet, accommodating from six to 10 people per row, for example.

Indoor / Outdoor Use: Bleachers designed for indoor or outdoor use have durable composition and finishes to protect from exposure to the elements and regular use. These bleachers are ideal for sporting events, fairs, school assemblies, and other uses.

Person / Seating Capacity: The person or seating capacity listed for select bleachers provides the maximum safe number of users at a given time, with users spread out and seated to balance weight distribution. Exceeding the listed seating capacity for a bleacher unit can void the warranty and result in damage to the bleachers or injury to users.

Rise: Rise refers to the height between the footboard or floor and the seat row just behind it. Many bleacher units feature a 12”-high rise for the front or bottom row and a 6”-high rise on the second and other back rows.

Seat Height: Seat height is the distance from the footboard, floor, or ground to the seat just behind it. For the first row or front seat on a bleacher unit this measurement may be 12”-high, with a 6”-height for the second, third, and other seating rows behind the first one.

Tread: Tread typically refers to the depth of stairs or bleacher seats.

4-Inch Sphere Test: The 4-inch sphere test is a general design rule for the components of a guardrail or fence, indicating that the posts or bars forming the rail are spaced in such a way that a 4” sphere does not fit through them. This is partly for safety regarding small children.
