Welded Steel Bar Grating
Gratings are steel bars that are forged to create a grid. Steel gratings have for long been the most favored choice of all gratings types owing to its durability, low maintenance costs, easy to install and customize and long life. We provide gratings manufactured from mild steel or stainless steel with various combinations of load bar depth and breadth.
Standard gratings are typically available in 6m x 1m or 20′ x 3′ panels.They can be produced with almost any combination of pitch size. Most commonly this is 41mm x 100mm or 30mm x 100mm.Load bearing bars of width 20mm to 100mm and thickness 2mm to 10mm can be used. Bars can be plain or with a serrated edge finish of various depths.Panels are available self-color or with a galvanized coating to international standards.
Materials
Mild Steel gratings with a galvanized finish are the most commonly used gratings for the majority of grating applications as they provide high strength and durability even in corrosive environments.
Stainless Steel Gratings can also be utilized in all applications where pressed steel gratings as they are manufactured with the same dimensions as galvanized pressed gratings. Stainless steel gratings with a galvanized finish are an excellent material for the most corrosive environments. They are commonly used in chemical applications, breweries, swimming pools and sewage treatment works.
Finishes
Steel gratings are further perfected with surface and treatment finishes to intensify the slip resistant and anti- corrosive characteristics of the gratings.
Surface Finish: Steel gratings are available with a plain or serrated surface. The serrated surface consists of a chain of notches on the upper surface of the load bar; these notches make the grating a non-slip surface to tread on.
Treatment Finish: Steel Gratings that are hot dip galvanized are also available. Galvanizing Gratings makes them ideal for use in corrosive environments. It protects the gratings from rust and prevents corrosive substances from coming into contact with the steel. Gratings are also provided in self color or painted.
