*Can be produced, if sufficient orders are available.

While standard lengths are mentioned in tables above, Bhilai Steel Plant can supply material in any fixed length in the range 6 - 13 m. Common Grades: IS 2062/1999 and SAILMA

Copper bearing structurals are also rolled as per customer's specifications. High strength quality light structurals as per the needs of TLT manufacturers also available.

Structurals are also available in the following foreign specifications: ASTM-A-36, JIS-G-3101-SS400, BS-4360 Grades 40A, 43A, 43B, 43C, 50B, 50C, EN-10025, Grades S-275 JO, JR, S-355 JO, JR, DIN-17100 ST 37.2/44.2 (all in semi-killed quality), if sufficient orders are available.

Straightening and Despatch

At BSP's Merchant Mill and Rail & Structural Mill each and every piece of each section is straightened through a straightening machine. Heavy structurals from R&S Mill are despatched piece wise while light structurals from Merchant Mill are clubbed in bundles of 8-12 tonnes in fixed length.

Angles from Merchant Mill for TLT manufacturers can be nested and packetted , after piece by piece inspection. Customers are requested to specify this, if required.
