Learn The Major Difference Between Molded & Pultruded Grating


     It goes without saying that choosing best FRP grating is not less than a rockets science one could ever face in industrial field. You don’t face to look into the features, or functions only, but there are particular criteria as well which can’t be neglected such as, which type of FRP grating you need for application

It’s easy to approach China FRP grating supplier without even determining what type of grating they specialize in, and how it can be profitable for any business. Let’s take an example of molded FRP grating and Pultruded FRP grating, do you know what makes them stand apart from each other?
Not sure, right? So let’s jump down to the main facts telling the main differences between them

 Difference Between Molded & Pultruded Grating

  Molded FRP Grating
   The molded grating is made by hand, and it is manufactured in an upside down waffle iron. It consist of 65% fiberglass and 35% resin, so what that means is you have highly corrosive resistant product. 

To ensure the quality and sturdiness of molded FRP grating? Molded grating is cast in one piece, this means there is no mechanical joint between bearing bars. The higher level of gum in formed gratings gives top notch erosion opposition and ideal effect obstruction

Also, molded fiberglass grating that has square mesh pattern provides a substantial load capacity for its bidirectional strength

The notable features of molded grating includes;
·         It has less wastage – An interwoven square mesh construction of molded FRP grating provides bi-directional strength, so you can cut FRP grating and freely use it on each panel

·         Extended life – You won’t need it replace molded FRP grating unlike other grating materials, neither you need to repaint it

·         Easy fabrication –  The molded FRP grating enables easy fabrication, one can easily cut it and integrate using standard tools in order to construct industrial platforms and walkaway

Pultruded Grating

Conversely with pultruded grating, its 65% glass and 35% resin, so it’s a very high strength product for long spans. Okay, so what does pultruded grating provide? It provides;

Corrosion resistance – Since FRP grating has high steel strength, so it won’t break down or get corroded 

Safety – Pultruded grating features an epoxy anti-skid coating for an enhanced traction

Extended life – This grating material has an ability to withstand elements of nature. The resin provides resistance to environment, and glass provides strength, apart from safety against fire 

Easy fabrication – The most highlighted advantage of pultruded FRP grating is that it has light weight panels. Hence they’re easy to transport and work with

Generally both molded and fiberglass grating are similar to some extent, yet the difference comes in the use of application where pieces will be installed (such as; industrial towers, catwalks, and platforms etc)
