Super Light Weight Steel Shuttering plates     Send Enquiry

  • Cheaper than normal shuttering plates. Rate ~Rs. 100/ft2
  • Lighter by ~40% compared to normal shuttering plates
  • Stronger : Takes slightly more load than normal angle shuttering
  • Reduced handling cost : Weight per piece is lesser, so it is easier for labor to carry.
  • The strength is achieved by optimization using 2D buckling equations and further validation using FEM

General Fabrication

Hoppers     Send Enquiry

The picture shows a general hoppers used at the end of conveyor belts. This hopper is fitted with polymer liner.
You will also find a vibration plate welded to the structure.
Above this hopper you will notice a frame structure.
We generally make these hoppers as per the drawing supplied by the customer. Given the requirement, we can also design and manufacture hoppers as per customer's requirements.

Agitator Hoppers     Send Enquiry

Agitator hoppers are conical shaped hoppers which are used in pairs.
These are bolted to each other, one of the hoppers being upside down.
These are completely sealed to prevent leakages of any sort. These are generally used to handling chemicals.
We generally make these hoppers as per the drawing supplied by the customer.

Large Sized Hoppers     Send Enquiry

The picture shows a larger hopper, something around 1.5 MT weight.
These generally find application in mining.

Feed Hoppers     Send Enquiry

These are used when the conveyor belts are much higher than material handling screens and other equipments. These are fitted with polymer liners, which are often thicker compared to what is used generally.
These generally find application in the mining industry.

Movable Hoppers     Send Enquiry

We also made special purpose hopper such as movable hoppers, which are fitted with special hardened steel or stainless steel liners. The movable hopper shown alongside, move to and fro on fixed rail tracks, so that bigger blocks also all down through the hopper and there is continuous operation of the system.
