Hot Dip Galvanized Serrated Grating Panel Manufacturers India | Sachiya Steel International Private Limited

Sachiya Steel International Private Limited is a leading manufacturer and exporter of hot dip galvanized serrated grating panels in India, supplying anti‑slip, corrosion‑resistant bar grating for industrial flooring, walkways, platforms, stair treads, and trench covers.

Why serrated HDG grating

Hot dip galvanized serrated grating combines the long‑life protection of a bonded zinc coating with a tooth‑profiled bearing bar that improves traction in wet, oily, or outdoor conditions.
The result is robust, low‑maintenance flooring and access systems with excellent drainage, ventilation, and slip resistance across harsh industrial environments.

What it is

Serrated grating is a steel bar grating panel where the bearing bar edges are machined or rolled with serrations to increase friction underfoot.
After fabrication, panels are hot dip galvanized so zinc metallurgically bonds to steel, shielding edges, welds, and cut areas better than most paint systems.

Manufacturing at Sachiya Steel International

  • Raw materials: Carbon steel to common project grades such as IS 2062 (E250/E350) or equivalent on request; stainless grades available for special environments.

  • Process: Electro‑forged (pressure‑welded) or fabricated grating with serrated bearing bars, cross bars, banding bars, and edge trims as per drawings.

  • Galvanizing: Hot dip galvanizing to recognized standards (e.g., ISO 1461/ASTM A123/IS 4759 equivalents specified by contract) for durable zinc coatings and robust edge protection.

  • QA/QC: Dimensional checks, weld integrity review, coating thickness measurement, visual inspection, and marking/traceability per approved QAP.

Feature Serrated grating Plain grating
Slip resistance Higher traction in wet/oily areas Standard traction for dry zones
Preferred use Platforms, catwalks, stairs, outdoor Clean rooms, light traffic, indoor
Cost vs. benefit Slightly higher cost, higher safety Lower initial cost, standard safety
Feature Electro‑forged Fabricated (hand‑welded)
Consistency Highly uniform welds Flexible for small batches/cut‑outs
Throughput High production efficiency Suited for complex custom pieces
Aesthetics Clean lines, repeatable quality Dependent on manual workmanship

Engineering benefits

  • Safety: Serrations add multiple micro‑edges that bite under footwear, reducing slip incidents on stairs, platforms, and ramps.

  • Durability: Hot dip galvanizing offers long service life versus paint in coastal, chemical, and outdoor atmospheres, including abrasion and handling during installation.

  • Performance: Open area improves drainage, airflow, and housekeeping, lowering stagnant liquid risks and minimizing buildup.

Where it’s used

  • Oil and gas, chemicals, and power generation platforms, including pipe racks, maintenance decks, and access walkways.

  • Water and wastewater plants, desalination facilities, and coastal infrastructure with aggressive corrosion exposure.

  • Metro, ports, bridges, industrial sheds, and public works requiring anti‑skid, low‑maintenance access systems.

Standards and compliance supported

  • Galvanizing: ISO 1461/ASTM A123/IS 4759 or client‑specified equivalents, with coating thickness checks as per standard.

  • Bar grating: NAAMM MBG 531, BS 4592, or project‑specified guides; base steel to IS 2062/ASTM equivalents as required.

  • Documentation: EN 10204 type 3.1 MTCs, galvanizing certificates, and third‑party inspection when specified.

Accessories and fixing

  • Clamps: Saddle clips, J‑bolts, and hold‑down systems to secure panels without welding to supporting steel.

  • Edging and frames: Banding bars, toe plates, and trench frames for safe load transfer and neat finishes.

  • Fasteners: Coated or stainless fasteners to match corrosion category and inspection preferences.

Packaging and logistics

  • Export‑ready: Palletized, strapped, edge‑protected bundles with panel maps and heat/lot traceability.

  • Marking: Itemized tagging per drawing and packing list for quick field identification and installation.

  • Dispatch: Consolidation from India with flexible INCOTERMS, project‑based delivery schedules, and port operations aligned to timelines.

Quality assurance

  • Dimensional and mesh verification against drawings, including bearing/cross bar pitches and tolerances.

  • Coating thickness measurement after HDG, with repair protocol for cut edges or site modifications as specified.

  • Optional load testing and slip resistance validation based on project criteria.

Ordering checklist

  • Material grade, surface type (serrated/plain), and finish (HDG preferred for corrosion).

  • Bearing bar size and pitch, cross bar pitch, panel size, and any toe plates, nosing, or frames.

  • Drawings for cut‑outs around pipes, columns, and equipment; clamp type and quantity.

  • Standards to comply with; documentation set (MTC 3.1, galvanizing certs); inspection and delivery terms.

Installation notes

  • Panels should be laid to panel map, oriented with bearing bars spanning supports to design span.

  • Use specified clamps at recommended spacing; avoid field welding unless approved by the coating/structural specification.

  • After any site cutting, apply an approved zinc‑rich repair coating as per project specification.

FAQs

  • What makes serrated grating safer than plain?
    Serrations create additional contact edges that enhance friction, significantly reducing slip risk on wet or oily surfaces.

  • Is hot dip galvanizing better than paint?
    Yes, hot dip galvanizing metallurgically bonds zinc to steel, protecting welds and edges and delivering longer service life in aggressive environments.

  • Can panels be supplied cut to drawings?
    Yes, panels are nested and cut to drawing, with banding, toe plates, cut‑outs, and frames integrated for ready installation.

  • Which standards can be met?
    Commonly requested are ISO 1461/ASTM A123/IS 4759 for galvanizing and NAAMM MBG 531/BS 4592 for grating; base steel per IS 2062 or equivalent.

  • How are panels fixed without welding?
    Use saddle clips or hold‑down clamps at recommended spacing to lock panels to support members while preserving coatings.
