Easy, Safe and Simple access solutions for cleaning, inspection and maintenance of cooling towers

Access platforms and walkways are fabricated from strong, corrosion resistant pultruded composite components and FRP moulded mesh which are generous 1200mm minimum width. Platforms enable service teams with tools and equipment - Easy, Safe and Simple access.

Pultrusion is a continuous process of pulling resins and reinforcing materials through a heated die, forming profiles of uniform cross section in a continuous length.

The pultrusion process involves:

Reinforcement 1 - Unidirectional roving, the reinforcing fibre that runs along the length of the profile.

Reinforcement 2 - The fibre mat is added in which is a multi-directional reinforcement.

The resin, typically vinyl ester for increased durability and strength.

The fibre is fully wetted with the liquid resin and pulled into a preformer for aligning the reinforcements.

Then into the heated die where curing takes place.

Once  the material enters the die, a surface veil may be added which enhances the final product's surface appearance.

All the resins used in the pultrusion process have a catalyst or hardener added when the resin is mixed which is activated at about 93°C. Consequently, as the wet reinforcement passes through the heated die, the product changes from liquid to a solid profile with all the reinforcement laminated within.

The product is the pulled through the die by "the puller ". The final product is then cut to the desired length.
