In using FRP grating, the principle is similar to that of metal grating, but the flexural modulus of elasticity of reinforced fiberglass bars is lower than that of steel. As a result, the allowable deflection has to be taken into consideration. The style of installation for FRP grating can be classified as secure installation, standard installation and 1% deflect installation.

Fixed Installation: Deflection : Span =1:180
Standard Installation: Deflection : Span =1:120
1% deflection installation: Deflection : Span =1:100

The data of load capacity provided by us comes from testing on the basis of 1% deflection, it is also the heaviest load suggested by us. The data, which is on the basis of secure installation or standard installation, can be calculated as per the following formula and the load data on the basis of 1% deflection.

Deflection of Grating = (Actual Load / Load on the basis of 1% deflection) * 1% deflection.
Unknown Load = (Known Span2 / Span2 of Unknown Load) * Load of Known Span
Deflection of Covered Grating = Deflection of Grating * High3 of Grating / (High of Grating + High of Covered plate)3

The above formula are based on experience, the result may not completely accurate, but it can be used as refernece. Actual loading is heavier than the calculation.

Tools for Installation

Cutting FRP grating requires less effort than cutting steel or alloys. FRP grating can be cut on site using Diamond Tip cutting blade fitted either to an Angle Grinder or Circular Saw. Even a hand saw can be used if necessary! We strongly suggest the use of a P2 Dust mask when cutting with a dust extraction unit if available Meanwhile other safety measures should be taken into account, such as gloves, protective clothing, goggles or safety glasses and P2 gauze mask when cutting and handling the FRP grating.
