Many industrial projects face serious issues due to the wrong choice of floor material or working platforms. One example occurred in a manufacturing company located in a large industrial area. Initially, they used steel grating for the walkway and machine platform areas. However, after a few years, the grating began to rust, become brittle, and even some parts broke due to constant exposure to chemicals and damp conditions.

The result? The company had to spend a significant amount on repairs or component replacements, in addition to the increased safety risks since the floor became slippery and hazardous. There was even a risk of production stoppages due to repairs or component replacements, leading to significant losses.

From this experience, the company decided to switch to Pultruded Grating made of fiberglass (FRP) as the main solution. The result? Much lower maintenance costs, longer service life, and better workplace safety.

Pultruded Grating is a type of grating made from fiberglass, produced through a pultrusion process that results in a lightweight yet strong product, resistant to corrosion and exposure to aggressive chemicals.

This product is commonly chosen for industries with harsh environmental challenges such as:
