For industrial security in Noida and Delhi NCR, the quick answer is: chain link fencing is the default perimeter solution - strong, see-through and economical - specified at 5 ft or taller, 2.5-4 mm wire, GI or PVC coated, and paired with angle-iron posts and (for high-security sites) razor wire on top. This guide from Garg Industrial Mesh, Sector 9 Noida, explains how to specify chain link for factories, warehouses and yards.
Why chain link for industrial security?
Chain link gives a see-through boundary that deters without hiding the site, withstands impact and climbing, and costs far less per running foot than a solid wall. For a factory or warehouse that needs a visible, durable perimeter, chain link is the standard - and it is fast to install and easy to repair.
Chain link specs for industrial use
| Spec | Light industrial | Standard factory | High security |
|---|---|---|---|
| Height | 4.5-5 ft | 5-6 ft | 6-8 ft |
| Wire gauge | 2.0-2.5 mm | 2.5-3.0 mm | 3.0-4.0 mm |
| Coating | GI | GI / PVC | PVC + razor wire |
| Post type | GI tube | Angle iron | Angle iron + concrete |
| Indicative price | Rs55-70/sqft | Rs70-90/sqft | Rs90-120/sqft |
How to choose the height
For a standard factory or warehouse, 5-6 ft is the baseline. For high-security sites (logistics yards, critical infrastructure), go 6-8 ft and add a razor-wire or barbed-wire top. Taller fences deter climbing; the see-through nature lets guards and cameras monitor the perimeter.
How to choose the wire gauge
Wire gauge (thickness) decides climb resistance. Light industrial (2.0-2.5 mm) is fine for low-risk boundaries. Standard factories use 2.5-3.0 mm. High-security sites use 3.0-4.0 mm wire that resists bolt cutters and climbing. Thicker wire costs more but is far harder to breach.
GI vs PVC coating for industrial fences
Bare GI is the budget default and works for most industrial use. PVC-coated chain link resists rust longer (important in humid or coastal-adjacent sites) and looks cleaner for visible frontages. For a raw industrial boundary, GI is usually enough; for a customer-facing frontage or a humid site, PVC pays off.
Posts and installation
Industrial chain link is mounted on angle-iron or GI tube posts set in concrete, spaced around 2.5-3 m apart, with tension wires and tie wires. For high security, posts are heavier and concreted deeper. A well-installed chain link fence lasts 15+ years with minimal maintenance.
