Standard Steel Gratings
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.

Steel grating offers the following advantages compared with steel grid sheets:
Steel grating has light weight, good strength, large carrying capacity and can save materials and cost. It offers good ventilation of light and wind, a modern sense, aesthetic appearance and anti-skid safety. It is also easy to clean, easy to installation and durable for uses.
Steel grating products are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering, and they offer the following the features:
Aesthetic outlook: Simple lines and silver appearance meeting the modern trend.Hot-dip galvanized treatment: Good rust-proof property, maintenance-free replacement.
Anti-theft design: The cover and the frame is joint with hinge offering security, safety and open convenience.
Savings investments: Large-span. Less lost for heavy load compared with cast iron products. Cost can be saved for the risk of being stolen or crushing one if cast iron is uses.
High strength: The strength and the toughness are much higher than cast iron. Can be used for terminals, airport and other large-span and heavy loading condition.
Specifications: More specifications and sizes optional for meeting various environment, load, span, sizes and shape
