Galvanized Metal Stair Treads Steel Stair Treads for Step Ladder
Most grating platform and walkway applications require stair treads to access the various levels that are inherent in most project applications.We offer a full range of aluminum grating tread profiles to meet the various demands in marketplace.Whether the project requires a standard maintenance access tread or a closer mesh and more pedestrain friendly product,we can offer a varity of competitive and cost effective products.
Treads are produced by steel gratings with surface to be hot galvanized or electrogalvanized. They are widely used as industrial platforms, aisle floors, railway bridge sideways, parking lots floors, etc.
Our sales team and engineering support group can helly with product specifiications regarding slip resistance surface(serrated) to meet the needs of our clients.
Raw Materials for grille stair tread:
1. Mild steel: high impact, high load application with low cost.
2. Stainless steel: anti-rust, good appearance, with higher cost than mild steel.
.According to whether the nosing to be used and methods of mounting to stringers,grating treads are classified into four types,expressed as AT1,AT2,AT3,and AT4.
1. Anti-slip treads: use serrated bearing bars to increase slip resistance property.
2. Stair treads: assembled by anti-slip strip and side plate.
3. Light duty type: suitable for using in normal loads.
4. Heavy duty type: suitable for using in heavy loads like docks and airports.
