About 1 2 GI Perforated Sheet

The specifications for industrial cable management systems, such as cable trays and raceways, are defined by key parameters including Material, Finish/Coating, Dimensions, and Thickness.

Since the specifications vary significantly based on the manufacturer and the required load class (light, medium, or heavy duty), the data below represents the typical range of specifications found in the industry.

1. Hot Dip G.I. (Galvanized Iron) Cable Trays

Hot Dip G.I. provides the highest level of zinc protection and is typically used for heavy-duty, outdoor, or corrosive applications.

Hot Dip G.I. Perforated Type Cable Tray

Specification Parameter	Typical Range	Standard/Reference
Material	Steel (Mild Steel/Carbon Steel)
Finish/Coating	Hot-Dip Galvanized (HDG)	Often complies with ASTM A123/A123M for coating thickness
Thickness	$1.6 \text{ mm to } 3.0 \text{ mm}$ (Heavier duty can be up to $6 \text{ mm}$ )	Varies by load requirement
Width	$50 \text{ mm to } 1000 \text{ mm}$
Side Rail Height	$25 \text{ mm to } 150 \text{ mm}$
Standard Length	$2.5 \text{ m to } 3.0 \text{ m}$
Hole Pattern	Perforated (round, square, or slotted) for ventilation

Hot Dip G.I. Ladder Type Cable Tray

Specification Parameter	Typical Range	Standard/Reference
Material	Steel (Mild Steel/Carbon Steel)
Finish/Coating	Hot-Dip Galvanized (HDG)	Often complies with ASTM A123/A123M
Thickness	$1.6 \text{ mm to } 3.0 \text{ mm}$ (Heavier duty can be up to $6 \text{ mm}$ )	Varies by load requirement
Width	$100 \text{ mm to } 900 \text{ mm}$
Side Rail Height	$50 \text{ mm to } 150 \text{ mm}$
Rung Spacing	Standard $150 \text{ mm, } 225 \text{ mm, or } 300 \text{ mm}$ (6, 9, or 12 inches)
Standard Length	$2.5 \text{ m to } 3.0 \text{ m}$

2. Pre G.I. Cable Tray

Pre-Galvanized (Mill Galvanized) is used for less demanding, typically indoor, dry environments.

Specification Parameter	Typical Range	Note on Finish
Material	Pre-Galvanized Steel (Mild Steel)
Finish/Coating	Pre-Galvanized (Zinc-coated before fabrication)	Exposed cut edges have minimal protection.
Thickness	$0.6 \text{ mm to } 3.0 \text{ mm}$	Typically lighter gauge than HDG due to environmental limitations.
Width	$50 \text{ mm to } 1200 \text{ mm}$
Side Rail Height	Up to $150 \text{ mm}$
Tray Type	Perforated, Ladder, or Channel
Standard Length	$2.5 \text{ m to } 3.0 \text{ m}$

3. Stainless Steel Cable Tray

Stainless Steel is selected for extreme corrosion, sterile, or high-purity environments.

Specification Parameter	Typical Range	Note on Material
Material Grade	SS 304 (Standard) or SS 316 (Marine/Chemical Grade)	SS 316 provides highest chloride resistance.
Finish/Coating	Natural Stainless Steel (Polished or Satin)	Relies on inherent chromium oxide layer for corrosion resistance.
Thickness	$1.6 \text{ mm to } 3.0 \text{ mm}$
Width	$50 \text{ mm to } 900 \text{ mm}$
Side Rail Height	$50 \text{ mm to } 200 \text{ mm}$
Tray Type	Perforated, Ladder, Wire Mesh (Basket)
Certifications	UL, NEMA VE 1, IEC	Required for many specialized projects.

4. G.I. Cable Raceway and Aluminum Raceway

Raceways (or Trunking) are enclosed systems for maximum protection.

G.I. Cable Raceway (Trunking)

Specification Parameter	Typical Range	Note on Function
Material	Steel (Mild Steel)
Finish/Coating	Pre-Galvanized or Hot-Dip Galvanized	HDG preferred for industrial floors/walls.
Thickness	$1.2 \text{ mm to } 3.0 \text{ mm}$
Width	$50 \text{ mm to } 1000 \text{ mm}$
Height/Depth	$25 \text{ mm to } 100 \text{ mm}$	Enclosed channel (often with a removable cover).
Standard Length	$2.5 \text{ m}$

Aluminum Raceway (Surface Mounted)

Specification Parameter	Typical Range	Note on Advantage
Material	Aluminum Alloy (e.g., 6063)	Lightweight and inherently corrosion resistant.
Structure	Solid or Split Cover	Used for surface-mounted, low-profile routing.
Thickness	$1.0 \text{ mm to } 10 \text{ mm}$	Varies significantly with profile design.
Width	$25 \text{ mm to } 300 \text{ mm}$	Typically smaller than industrial cable trays.
Finish	Architectural Clear Anodized or Powder Coated	Chosen for both aesthetics and durability.
Standard Length	$2.5 \text{ m to } 3.05 \text{ m}$ (10 ft)
