• Back Column Post – 1100 mm – 100 X40 X 15 X 2 mm – Lipped Channel – 3 nos
• Rafter – 3300 mm – 100 X40 X 15 X 2 mm – Lipped Channel – 2 nos
• Purlin – 5100 mm – 41 X 41 X 2 mm – Strut Channel – 4 nos
• Fasteners – M 10 X 30 mm- Gold Plated bolts – 28 nos
• Mid clamp – 16 nos
• End clamp (35/40 mm)- 8 nos
• M8 X 35 mm, Plain washer and spring nut
• Strut channel design makes it suitable for any type of solar panels of any brand

GI pipes come at standard Length 6 Meters. Grade 1 are TATA Steel, JSW Steel & SAIL. Standard size charts found https://www.deltaware.in/product/steel-pipe-round-gi/ ↗

1 length is 19.685ft. Each set of poles can be 8+7 = 15 ft above plate and below ground can be 2.3 ft each. 1400mm gap between two cross section tubes. Panel Information: Size: 2272 mm (L) x 1133 mm (W) x 35 mm (T) Weight: 32.5 kgs Holes: 1400 mm or 1000mm (8 Nos 14*9 hole) or 400mm(4 Nos 10*7 hole) Distance between NS - 2000mm or 2200mm(for GI sheet) Distance between EW - 3400mm Round pipe 1 1/2”inch or 40mm Bore 21.35kg per length GI rectangular pipe 2.5inch*1.5inch 60mmx40mm 2.90mm thickness @26.09kg per Length 3.2mm thickness @28.65kg per Length Galvanized Plain Sheets 8ft*3ft or 8ft*4ft. Need 8*12ft size.

Galvanized Steel: 10 Gauge = 3.51 mm Galvanized Steel: 16 Gauge = 1.613 mm

In India for HVAC, 0.5mm (26 gauge), 0.6mm (24 gauge), 0.8mm (22 gauge), 1mm (20 gauge). 1.2mm (18 gauge), 1.6mm (16 gauge) thick sheets are generally used.

Approximate rates - Rectangular Pipe ₹105/kg, round pipe ₹95/kg, Plain Sheets ₹45/kg
