Frequently Asked Questions
Common questions about our foundation and anchor bolt manufacturing and supply.
-
What are foundation bolts?
Foundation bolts are heavy-duty fasteners cast or installed into a concrete foundation to anchor structural columns, machinery, towers and equipment. They transfer tensile, shear and uplift loads from the structure to the foundation. Common types include L-type, J-type, T-type and plate-type foundation bolts.
-
What sizes of foundation bolts does E S Haji & Co manufacture?
We manufacture foundation bolts from M12 to M100 diameter as standard. Brace rods can be supplied in single lengths up to 12 metres on request. All sizes can be customised based on project drawings.
-
What is the difference between foundation bolts and anchor bolts?
Foundation bolts are typically pre-installed (cast-in-place) when concrete is poured, used to anchor columns, towers and heavy machinery. Anchor bolts is a broader term that includes both pre-installed and post-installed bolts. All foundation bolts are anchor bolts, but not all anchor bolts are foundation bolts.
-
Which standards do your foundation bolts comply with?
Our foundation and anchor bolts comply with ASTM F1554 (Grades 36, 55, 105), IS 5624, DIN 529 and ISO 898-1 in bolt grades 4.6, 5.6, 8.8, 10.9 and 12.9 depending on application.
-
Do you offer custom foundation bolts to drawing?
Yes. Custom foundation bolts are our specialty. Send us your drawings and project specifications and we'll manufacture to exact dimensions, grade, finish and quantity. We supply MTCs with every batch.
-
Do you deliver foundation bolts across India and abroad?
Yes. We deliver PAN India to all major industrial hubs including Mumbai, Bangalore, Hyderabad, Pune, Delhi NCR, Kolkata, Ahmedabad and Coimbatore, and also serve export projects abroad.
