Structural Steel Fabrication:
All of APMFG bleacher designs uses very complex angles, laser cut hole patterns, heavy plates, round structural extra heavy pipe grade B, solid rounds, flat bar, I beams, channels and heavy schedule pipe machined for cross braces. All materials are ASTM A36 Grade B and are designed with tight tolerances along with custom angles for an exact fit. All fabrication is done with continuous welding inspection.
Concrete ramps were formed and set to the ada slope along with Schedule 80 Steel Pipe guard rails and ada hand rails.
