How does fibreglass gratings strength compare with steel?
For pedestrian traffic and medium loadings, fibreglass grating is perfectly adequate. On some occasions it can be used in heavy load situations. For example in narrow drainage gullies. As a basic guide, our 25mm grating will comfortably withstand 1/3 ton per square metre and the 38mm 1/2 ton per square metre. These figures are based on 1 metre wide gratings supported on 4 sides. If the width is smaller and the correct support is provided, these figures can be multiplied many times. For example, at 300mm wide, our 38mm grating can withstand loadings in excess of 12 tons!
