Warehouse & Godowns
Industrial-strength materials for pre-engineered warehouses and storage structures
Shop Warehouse Materials →Warehouses and godowns are the commercial backbone of Andaman's growing trade and logistics sector. Building a robust, cost-effective storage structure requires the right combination of structural steel members, long-span roofing, and durable cladding. Saran Traders supplies the complete range of materials for pre-engineered and conventional warehouse construction — from structural angles and channels to wide corrugated roofing sheets and HDPE canvas side cladding.

Step-by-Step Guide
How to approach your warehouse & godowns project
Plan Layout & Structural Design
Define the bay width, height, and number of bays based on your storage requirement. Standard warehouse bays are 6m to 9m wide. In Andaman's cyclone zone (Wind Zone V), engage a structural engineer to design for IS 875 Part 3 wind loads — this is particularly critical for large-span roofs.
Foundation & Column Base
Prepare individual pad footings for each column. Anchor bolts must be precisely positioned per the column layout. Cast column base plates into the footing with correct projection for bolt threads before backfilling.
Erect Columns
Erect columns (GI or MS pipe, typically 3 inch to 6 inch diameter for small warehouses) with temporary guy wires for stability. Check plumb on two axes before final grouting. For larger spans, hollow section (SHS or RHS) columns or I-sections may be required per design.
Install Rafters & Purlins
Fix MS or GI pipe or angle rafters across the column tops. Connect purlins at designed spacing (1.2m to 1.8m typically). Ensure all connections use proper cleats and bolts, not makeshift welds alone — bolted connections are more inspectable and maintainable.
Lay Roofing & Side Cladding
For large warehouses, use long-length corrugated or trapezoidal profile sheets (up to 12m lengths available) to minimize end laps and improve waterproofing. Fix with self-drilling screws at every purlin. Extend eave overhang by at least 600mm for protection against Andaman's driving rains.
Shutter Installation
Install strong shutters using strong profiles and assemblies to secure the storage structure.
Finishing & Drainage
Install ridge ventilators if the godown stores heat-sensitive goods. Lay concrete floor with minimum M20 grade and MS mesh reinforcement for forklift loads. Install proper perimeter drainage channels and downpipes to manage Andaman's high-intensity monsoon rainfall.
Frequently Asked Questions
Expert answers to common questions about warehouse & godowns
QWhat is the most cost-effective roofing choice for a warehouse in Andaman?›
Corrugated galvanized iron (GI) roofing sheet in 0.50mm thickness offers the best cost-to-performance ratio for warehouse roofing. For better longevity, upgrade to 0.50mm pre-painted (color-coated) sheets with 150GSM Al+Zn coating — the additional cost is recovered over 5 years through reduced maintenance. For very large spans, consider trapezoidal profile sheets which allow wider purlin spacing, reducing the number of purlins needed.
QWhat structural steel sections are best for warehouse frames in Andaman?›
For small godowns (spans up to 6m): GI or MS round pipes for columns and rafters, with angle purlins. For medium warehouses (6 to 12m span): MS channels or I-sections for rafters, MS pipe columns. For large-span warehouses (12m+): Pre-engineered steel frames using tapered I-sections are most efficient structurally. All exposed steel must receive primer and paint or hot-dip galvanizing in Andaman's coastal environment.
QCan GI pipe structures handle Andaman's cyclone wind loads?›
GI pipes can be used in warehouse structures if properly designed for Andaman's Wind Zone V conditions (design wind speed: 55 m/s as per IS 875 Part 3). The connections — column base, rafter-to-column, purlin-to-rafter — are the critical points. They must be bolted and welded per structural calculations, not simply friction-fit. Do not cut corners on connections for structures in cyclone zones.
QHow do I protect the warehouse floor for forklift operation?›
Use M25 grade concrete with a minimum thickness of 150mm for forklift traffic. Include a welded mesh or TMT bar reinforcement (8mm dia. at 200mm c/c both ways) at mid-depth. Joint spacing should be maximum 4m x 4m to control cracking. A surface hardener significantly improves wear resistance for warehouse floors in high-use areas.
QWhat permits are required to build a godown in Andaman?›
Building permits in the Andaman Islands are issued by the Port Blair Municipal Council (PBMC) for Port Blair areas and respective Local Bodies for other islands. You will need: approved structural drawings, site plan, and a certificate of commencement from a licensed engineer. The Andaman Administration also has specific regulations for structures near the coast, forest boundaries, and tribal reserve areas — verify your plot's regulatory status before construction.
