By Material & Finish
Galvanized Steel Grating
Hot-dip galvanized after fabrication for long-term corrosion protection on outdoor platforms, walkways and trench covers.
View product
Stainless Steel Grating
SS304/316L grating for chemical, food-grade, coastal and hygienic environments — passivated or electro-polished.
View product
Aluminum Grating
Lightweight, corrosion-resistant aluminum bar grating for architectural, marine and light-to-medium duty platforms.
View productBy Construction
Welded Steel Grating
Press-welded bearing bars and cross bars — the most common, economical grating for platforms, walkways and trench covers.
View product
Press-Locked Grating
A mechanically locked grid with clean lines and flexible spacing options for industrial flooring, screens and projects where appearance matters.
View product
Swage-Locked Grating
A mechanically assembled grating construction commonly used for lightweight aluminum platforms, walkways and access systems.
View productBy Performance
Serrated Steel Grating
Serrated bearing bars for added traction where wet, oily, snowy or inclined conditions are identified.
View product
Heavy Duty Steel Grating
Heavy bearing bars for forklift, truck and equipment loads — engineered against span and support conditions.
View product
Light Duty Steel Grating
A material-efficient grating starting point for pedestrian and light maintenance access after span and load confirmation.
View productBy Form & Custom
Stair Tread Grating
Grating stair treads with nosing, end plates and fixing holes — bolted or welded to industrial stair stringers.
View product
Trench Cover Grating
Drainage trench covers from pedestrian walkways to heavy vehicle crossings, framed and hinged options available.
View product
Compound Steel Grating
Bar grating combined with checkered or solid plate where load support and small-object containment must work together.
View product
I-Bar Grating
An I-shaped bearing-bar profile that reduces material and panel weight where its verified load range suits the project.
View product
Custom Irregular Grating
Drawing-based non-rectangular panels with notches, cut-outs, curved edges and project panel numbering.
