GRP Pultrusion - A wide range of pultruded profiles are available from stock including round tubes, box sections, angles, U beams. ladder rung, I beams, handrails, kick plate, embedment angle and much more. Profiles are generally supplied in 6000mm lengths for your own constructions or alternatively we would be pleased to quote you for building and installing your pultruded fabrications and structures, ladders, working platforms, walkways, stairs and handrails etc.
Composite pultruded structures made from our profiles are substantially lower in cost than steel and cost competitive with stainless steel. Our pultruded profiles are made from glass reinforced isophthalic polyester resin with a polyester surface veil. This combination gives excellent corrosion resistance and weatherability at an economic cost.
Our profiles are manufactured to ISO9002 and conform to EN ISO 13706. You are very welcome to perform any tests you require on our materials. Samples are supplied free of charge. Custom profiles can be manufactured to order using our low-cost tooling. Please ask for details. Please call us for a copy of our corrosion resistance data sheet and price lists. Profiles can be cut to your requirements free of charge. We can also machine profiles in our workshop often free of charge.
An introduction to the pultrusion process. The raw materials for pultrusion include a liquid resin mixture containing resin, fillers and specialised additives combined with flexible textile reinforcing fibres. To achieve reinforcement, materials in continuous forms such as rolls of fibreglass mat and doffs of fibreglass roving are used. During the pultrusion process, the raw materials are pulled through a heated steel forming die using a continuous pulling device. When the reinforcements are saturated with the resin mixture ("wet-out") in the resin bath and pulled through the die, the resin becomes hardened due to the heat from the die and the cured profiles are thus formed in the same shape as the die.
This series of 5 pictures shows in detail the pultrusion process. Picture 1 shows the glass reinforcement filaments on large rolls all heading towards the tool. Pictures 2 and 3 show the glass reinforcement being dragged through the resin in the wetting out process. Picture 4 shows the final surface veil being loaded and finally picture 5 shows the finished product emerging from the tool.

Embedment angle Green only to suit 25mm, 38mm and 50mm grating
Embedment angle is a unique pultruded fibreglass angle that can be embedded into concrete ready for our grating panels to be installed. This profile is currently stocked for 25mm, 38mm and 50mm thick gratings and is a similar colour to our green gratings to give a professional finish.
The angle is manufactured from isophthalic resin for high chemical and corrosion resistance.
