Tunnel Rock Bolts
Tunnel Rock Bolts supplied by Srons Engineers are ground‑support fasteners fabricated from high strength steel. The bolts are offered in steel grades SMW‑500 or BHRB‑500, covering Fe415 to Fe550, and are supplied with a zinc coating for corrosion resistance. Standard dimensions include diameters from 20 mm to 32 mm and lengths between 1.8 m and 3.6 m, matching typical tunnel reinforcement requirements.
The material choice reflects the need for high tensile capacity in underground environments. SMW‑500 and BHRB‑500 grades are common in rock bolting, providing tensile strengths around 500 MPa and yield strengths near 415 MPa, which align with industry practice for mining and civil works. The zinc coating extends service life in moist or acidic rock conditions, a standard protective measure across similar products worldwide.
These bolts are used by mining contractors, tunnel construction firms and civil‑engineering contractors for shaft reinforcement, slope stabilisation and tunnel excavation. Buyers typically request batch certification, test reports and conformity to standards such as ASTM A193 or EN 10270. Since the listing does not disclose minimum order quantity, price or specific Incoterms, interested importers should contact Srons Engineers to confirm trade terms, lead times and shipping arrangements.

Sourcing Tunnel Rock Bolts from Srons Engineers - India Import Guide
Before ordering, verify the steel grade, diameter, length and coating details against your project design. Ask Srons Engineers for material test certificates and a coating thickness report to ensure the bolts meet the required mechanical and corrosion criteria. Confirm that the bolts comply with the standard (ASTM A193 or EN 10270) relevant to your region.
Logistics should be clarified early; typical shipments from Ludhiana use sea freight from the nearest Indian port, with Incoterms such as FOB or CIF negotiated per order. Inquire about lead times, container loading capacity and payment terms, as the listing does not disclose these specifics. Align payment schedules with document verification to protect both parties.
Arrange a third‑party inspection at the factory or upon arrival to validate dimensions, coating integrity and tensile performance. Request a pre‑shipment inspection report and retain the original test certificates for customs clearance. Following these steps will help ensure the rock bolts arrive as specified and perform reliably in your underground projects.
