What Our Clients Say
We sourced square-plate anchor bolts from E S Haji & Co for a wind turbine foundation in Maharashtra. Weld quality and bearing area were exactly as specified — bolts handled severe uplift loads without any issue. Their team flagged a drawing discrepancy early during engineering review, saving us a costly site rework. MTCs were provided on time and we will be placing repeat orders for upcoming phases.
Gopal K. Civil Lead, Renewable EPC, PuneE S Haji & Co manufactured double-nut plate bolts to our drawing for a high-vibration press foundation. After months in service, bolts remain tight with zero loosening. Dimensional accuracy and surface finish were consistent across the full batch. Their lead time was better than every other supplier we had approached for the same requirement.
Ravi S. Project Engineer, AhmedabadFor a chimney stack foundation in Chennai, we needed heavy plate-type bolts with full weld inspection documentation. E S Haji & Co delivered exactly to drawing with MTCs and weld reports — structural team had zero punch points on the anchor bolt supply. Their in-house manufacturing gave us full confidence in quality control throughout the project.

Frequently Asked Questions
Common questions about our plate type foundation bolts manufacturing and supply.
-
What is a plate type foundation bolt?
A plate type foundation bolt is an anchor bolt with a steel plate welded to the embedded end. The plate creates a large bearing surface in the concrete, giving very high pull-out and tension capacity - much greater than a bent bolt of the same diameter.
-
When should I use plate type bolts?
Use plate type foundation bolts where uplift and tension loads are severe - tall structures, wind turbines, heavy or vibrating machinery, stacks and seismic foundations. The welded plate distributes load and reduces local concrete stress.
-
What plate shapes and thicknesses do you offer?
We supply square, round and rectangular end plates, typically 8 mm to 40 mm thick, sized to your design load. Plate geometry, thread length and embedment are produced to drawing.
-
What welding process is used for the plate?
We use full penetration or fillet welding depending on the design load and plate thickness. All welds are inspected for integrity before dispatch, and weld inspection reports can be provided on request.
-
What sizes and grades are available?
Plate type foundation bolts are manufactured from M12 to M100 in grades 4.6, 5.6, 8.8, 10.9 and 12.9, conforming to ASTM F1554, IS 5624, DIN 529 and ISO 898-1.
-
Do you provide MTCs with plate type bolts?
Yes. Every batch is supplied with Mill Test Certificates (MTCs) confirming material grade, chemistry and mechanical properties, with weld inspection on request.
-
Can you supply plate type bolts PAN India?
Yes. We deliver across Mumbai, Bangalore, Hyderabad, Pune, Delhi NCR, Kolkata, Ahmedabad and all major industrial hubs, with custom manufacturing to drawing.
-
Can plate type foundation bolts be hot-dip galvanised?
Yes. Hot-dip galvanising is available and recommended for outdoor, coastal and high-chloride environments. Zinc plating and black oxide finishes are also offered depending on project requirements.
