Standard Rise Bleachers
Standard bleachers generally have a rise between seat levels of 8”. A low rise is 6”. A Standard rise bleacher will provide better downward viewing over the spectators in the next lower seat row then low rise bleachers provide. Standard rise bleachers are available with a variety of options. (Review your local codes for specific requirements.) Single (Standard) or double (Preferred) walk planks are available as required by customer needs. Other options include built-in steps and handrails, and side and back safety rails. Depending on configuration, these bleachers conform to the current IBC/ICC Standards on Bleachers. Contact your factory representative for more information.

Each plank is constructed from extruded 6063-T6 mill finished aluminum. Planks are finished with clear or colored powder coat to prevent oxidation. The planks are 9 5/8” wide by 1 ¾” thick with built in ribbing for added strength. Planks will vary in length of 9’, 15’, 21’, and 27’. Other lengths are available on special order. The topside of each plank has a low profile tread to improve traction. Aluminum end caps are pre-attached prior to shipping. Optional plank colors are available.
The support frames are fully welded angle iron construction and powder coated (Black) to provide for years of low maintenance. Standard frames are offered in sizes up to 6 seat levels with the first seat level starting at 17” above the floor. For bleachers requiring more than 6 seat levels, add-on framing can take this design up to 8 or 10 seat levels. Frames are normally spaced on 6’ centers and cross-braced for independent rigidity. Two frames are required with 9’ planks, 3 frames with 15’ planks, 4 frames with 21’ planks and 5 frames with 27’ planks.
Most guidelines recommend safety railing on all bleachers where seats or walk planks are higher than 30” above the adjacent ground elevation, most guidelines recommend safety railing. Although safety railing can vary in design, this bleacher system uses railing that has vertically positioned slats with less than 4” spacing. This type of safety railing contributes to greater safety since it does not promote climbing because it does not use horizontal cross members.
This bleacher system can be configured with walk planks as either a single plank (Standard) or double planks (Preferred) depending on customer requirements. Important, most safety guidelines recommend against openings that are greater than which a 4” diameter sphere can pass through whenever that opening is higher than 30” above the adjacent ground elevation. Therefore, double walk planks are normally used for seat levels that start at five and higher and also incorporate a back panel.
This bleacher system can be configured with or without steps/aisles. Local Codes and Guideline dictate those requirements. Step location and spacing depends on the length of planking and number of support frames used. Steps will normally be provided hand railing in accordance with the current IBC/ICC Standards on Bleachers as required for customer needs.
A precut-treated 2 x 4 wood runners are attached to the bottom of each bleacher frame. This wood runner is provided to reduce the chance of damage to the surface on which the bleacher assembly sets and to provide a barrier between the ground and bleacher when used outdoors. Regardless, bleachers must always be positioned on hard level surfaces to provide for the best bleacher stability.
Bleachers come in a variety of sizes. They are purchased based on the number of seat rows, length of planks, standard vs. preferred and with or without steps. To determine the size of bleacher you will need, consider a requirement of 18” per spectator. For example: A three row x 15’ bleacher w/o steps will seat 30 people. Discuss your options with a qualified factory representative. For additional information, consult your local building codes and bleacher safety recommendations provided by the current ICC/ANSI 300 standards on Bleachers.
