What Drives Sourcing Price Differences?
In B2B solar structure procurement, buying the cheapest option can lead to structural failures under cyclonic wind shears. Below are the key engineering specifications that dictate structural pricing:
1. Raw Metal Standards: IS 2062 Grade E250 vs E350
Grade E250 steel has a yield strength of 250 MPa, suitable for general residential structures. Grade E350 steel offers a higher yield strength of 350 MPa, allowing for longer spans and reduced overall weight. Grade E350 steel carries a premium of ₹3,000 to ₹5,000 per Metric Ton but reduces total tonnage requirements.
2. Post-Fabrication Galvanizing: IS 2629 / IS 4759 Compliance
Poorly galvanised steel will rust within years. SOLBE post-fabricates all steel parts before placing them in a molten zinc bath (galvanising) to create a metallurgical zinc coating in accordance with IS 2629 and IS 4759. Cheap alternative structures use pre-galvanised mill sheets (typically under 20 microns coating) which rust quickly at punched slot holes.
3. Anodisation Micron Layers for Aluminium: IS 1868 Compliance
Aluminium profiles are anodised to protect the metal against marine atmospheric corrosion. Coastal locations require a thicker 20-micron layer (AA20), whereas dry inland regions are suited to a 15-micron layer (AA15). Higher micron profiles resist salt spray corrosion for 25+ years.
Pricing & Procurement FAQ
Common questions from B2B purchasing managers and solar EPC engineers.
Why are solar mounting structure prices quoted per kg for GI and per meter for Aluminium?
GI structures use thick heavy steel columns and purlins where the total material weight dictates manufacturing costs. Extruded aluminium structures are hollow, lightweight profiles where extrusion die shape, linear length, and wall thickness dictate cost rather than total weight.
How do raw material commodity price changes affect my quotation?
Because steel and aluminium are highly liquid commodities linked to the London Metal Exchange (LME) and national steel market indices, B2B quotations are generally valid for 7 to 10 days from issuance. For large projects, pricing can be locked during order confirmation with bank guarantees.
Does the pricing include STAAD Pro calculations and certified drawings?
Yes. For all commercial and industrial volume orders, our design team provides STAAD Pro structural wind-load certification sheets and 2D/3D layout drawings at no extra cost, ensuring compliance with local wind and load standards.
