Pultruded Gratings
Pultruded gratings are manufactured of pultruded fiberglass bars that are then assembled. Pultruded gratings are the best replacement to traditional material gratings due to the superior advantages of fiberglass and the composites, especially while been applied to those where corrosion resistance is required. The main properties of pultruded gratings are:
*High strength-to-weight ratio
*Chemical resistant, corrosion resistant
*Anti-UV
*Long serving life (usually over 20 years outdoor)
*Dimension stability
*Electrical resistant
*Heat resistant
*Electromagnetic wave transparency & resistance 

Huayuan (HAMC) use polyester resin, phenolic resin, epoxy resin and at the latest, PU resin for pultrusion process. PU resin pultrusion is the latest technology in the whole world. Huayuan (HAMC) have started PU resin pultrusion for over 3 years and have created successfully the most complex profile in the whole world using PU resin.
