Manufacturing Method & Tolerances
Manufacturing Method:
Rod is threaded and inserted inside a steel sleeve which can be tack-welded or slotted as per design. Plates, stiffeners, or washers are welded/assembled based on the foundation requirements. Finishing is applied based on site conditions and corrosion environment.
Tolerances:
- Threading: IS 1363 / DIN 976 / ASTM A307
- Dimensional: ±1mm on rod and pipe sizes
- Sleeve depth and rod projection as per project specs
Applications & Usage
- Used in bridge and metro pillar foundations
- Ideal for machine base supports and vibration areas
- Perfect for tower base plates and pole mounting
- Used in precast elements and construction templates
- Helps with bolt alignment in deep foundation casts
