Introduction to Coated Mild Steel Gratings
Coated Mild Steel (MS) Gratings are rigid, load-bearing panels fabricated from IS 2062 grade steel bars and finished with long-life protective coatings. Engineered for walkways, trenches, platforms, stair treads, and mezzanines, these gratings combine high strength with slip resistance and fast drainage. With surface options like hot-dip galvanizing, epoxy/polyurethane painting, powder coating, and bitumen, coated MS gratings deliver durable performance in corrosive, outdoor, and high-traffic industrial environments while maintaining a clean, professional look across utilities and plants.

Manufacturing, Coatings & Performance
Gratings are produced by welding or press-locking bearing bars with cross bars at precise pitches, followed by edge capping and surface finishing. Coating selection depends on service conditions—hot-dip galvanizing (HDG) to BS EN ISO 1461 for sacrificial corrosion protection; epoxy/PU systems for chemical resistance; powder coat for aesthetics; or bitumen in buried applications. Correct bar depth, thickness, and span ensure deflection control and load class compliance. Learn about coating standards, QA checks, and customization at Vishal Engineers.
Types of Coated MS Gratings
- Welded Steel Gratings — robust, economical panels for platforms, catwalks, and trench covers.
- Press-Locked Gratings — clean, architectural finish with tight tolerances for uniform appearance.
- Serrated (Anti-Slip) Gratings — enhanced traction for oily, wet, or outdoor surfaces.
- Heavy-Duty Vehicle Load Gratings — thicker bearing bars for forklifts, trolleys, and driveway trenches.
- Stair Treads & Frames — integrated nosing with bolt-on or welded install for safe access.
Key Features & Specifications
- Material: IS 2062 E250/E350 mild steel; bearing bar depth 20–75 mm; thickness 3–6 mm.
- Pitches: bearing bar typically 30–40 mm; cross bar 50–100 mm for strength and drainage.
- Coatings: HDG (typ. 70–100 µm), epoxy/PU paint systems, powder coat, or bitumen upon request.
- Surface: plain or serrated top; edge-banded; lifting lugs, clamps, and toe plates available.
- Compliance: fabricated to drawings with load/deflection criteria and dimensional QA checks.
Applications of Coated Mild Steel Gratings
- Industrial walkways, platforms, and mezzanines in factories, refineries, power plants, and warehouses with safe slip-resistant access for operators and maintenance teams.
- Drainage and trench covers for ETP/STP plants, process lines, and utility corridors allowing free flow of fluids while providing heavy-duty pedestrian or vehicle load capacity.
- Cooling towers, pump houses, boiler areas, and sub-stations where corrosion-protected gratings ensure reliability under wet, humid, or chemical-laden conditions.
- Stair treads, catwalks, and rooftop service decks in commercial buildings, airports, metro stations, and shipyards with strong ventilation and minimal cleaning effort.
Benefits of Choosing Coated MS Gratings
- Long-Term Corrosion Protection – HDG and paint systems shield steel from moisture, salts, and chemicals, extending service life and reducing lifecycle costs in harsh environments.
- High Strength-to-Weight Ratio – Optimized bar geometry offers excellent load capacity with controlled deflection across standard spans, easing handling and installation.
- Superior Safety & Drainage – Open grid with optional serrations improves grip, visibility, airflow, and fluid runoff, minimizing slip risks and housekeeping downtime.
- Custom-Built Versatility – Tailored sizes, spans, frames, cut-outs, and accessories (clamps, handrails) seamlessly match site drawings and installation constraints.

Installation, Maintenance & Safety Tips
- Select bar depth/thickness to meet load and deflection limits; verify span against traffic class.
- Use galvanized/stainless clamps and hardware to avoid bimetallic corrosion at connections.
- Seal cut edges after on-site trimming; apply zinc-rich paint or touch-up per coating guidelines.
- Plan drainage fall and orientation of serrations toward travel direction for better traction.
- Schedule periodic wash-downs and inspection of coating integrity, welds, and fasteners.
