Product Description

Galvanized Steel Stair Treads & Bar Grating

High-strength steel bar grating constructed from carbon steel, aluminum steel, or stainless steel. Ideal for outdoor, warehouse, platform stairway, and catwalk applications.

Manufacturing Methods

Welded Grating

The most commonly used and economical design suitable for most industrial applications. Manufactured by welding the bearing bar and cross bar intersection, typically with automated forge welding equipment or professional manual welding. Available in carbon steel or stainless steel.

Dovetail Pressure Locked

Insert the cross bar into the pre-punched bearing bar and hydraulically deform it to lock it in place. The cross bar here is usually a straight plate shaped like a bearing bar.

Swaged Pressure Locked

Assembled by inserting pre-punched bearing and cross bars into an "egg-crate" configuration and deforming the cross bars under intense hydraulic pressure. Available in all materials and ideal for architectural and ornamental applications.

Welded Swaged Pressure Locked

An upgraded version of the swaged pressure locked design. Each intersection is manually welded once to make it stronger and capable of withstanding heavier loads.

Surface Types

Smooth Surface Grating
Serrated Surface Grating
