FRP Grating Production Process

There are three main types of fiberglass grating production process: reciprocating filament winding technology, continuous filament winding technology and centrifugal pouring process.

The manufacturers using reciprocating system of filament winding process tubes are more than manufacturers in other two production technology manufacturers in the world, one of the reasons is the pipes made in reciprocating filament winding process have a wider range of USES, its applicability is more better.

All panels have five surface choices: concave top, grit top, plain top, smooth top, and covered top, Standard color:



How to choose?


1. Make sure how to use fiberglass grating? such as the manufacturer of the carwash use the FRP grating as the loading plate to wash the cars.

2. After determining the purpose of fiberglass grating, it is the time to determine the size of fiberglass grating. According to the relevant introduction of the manufacturer, we can have a certain understanding of fiberglass grating. For example, in the car washing, you can choose the fiberglass grating with 2.5cm thickness or 3.8cm thickness. In the electroplating equipment factory, the common used size is 2.5cm thickness fiberglass grating. In sewage treatment plants and chemical plants, 3.8cm thickness fiberglass grating is mostly used.

3. After the appropriate thickness of fiberglass grating have been selected, the size of the grid plate should be calculated. In the car wash. The position size of a car wash is 1.220m*2.440 m, while the size of the fiberglass grating is 1.220* 3.660, which requires to be cutted before intallation.

4, select the appropriate raw materials for production to meet the requirements of FRP grating, such as you need to choose resin with higher corrosion resistance in production for fiberglass gratings used in the chemical plant or a sewage treatment plant



How to install?


It will need special equipment which can be refitted by tractor or car to lay up fiberglass gratings. Glass fiber grating products per roll film marked with orange and blue marking is at each end, before start laying, you should choose plastic face to determine the tag color each at both ends, to invoid make side without glue wrong in construction, When laying Fiberglass gratings, it is necessary to maintain it is smooth, tighten, both sides aligned, make it is tension effective, after the laying press it wih a clean steel roller rolling again to make sure it is clean and bright, more color.

The common Fiberglass gratings has a self adhesive and no self-adhesive.
The self-adhesive can be laid directly on the flat base, and the stainless steel ring and steel screws are usually used without self-adhesive.
The normal section is used without self-adhesive Fiberglass gratings,. The materials required are:
a.50 x 50 x 0.3mm and be flat and unward-looking
b. 2 inches steel nails.

To Use steel nails in laying Fiberglass gratings, firstly the end clamp ring and steel nail fixed in the spill cloth glued layer asphalt on the base of the steel nail hammer and nail into. Then tighten and segment the grille, with each length of 2 ~ 5m. It can also be segmented according to the gap between the joints and the joints of steel nails. The glass fiber is in a straight tension when the grid is tight.
The Fiberglass gratings is connected vertically, the width is not less than 20mm, the transverse lap width is not less than 15mm, and the longitudinal lap should be placed on the latter one according to the direction of the asphalt spreading. The steel nails can not be nailed to the Fiberglass gratings at fixed time, and the steel grating can not be hit directly with the hammer. If the steel nails are broken or the card ring is loose, it needs to be fixed again. After the Fiberglass gratings is laid, it is necessary to use the rubber roller to moderate the stability, so that Fiberglass gratings and the surface of the original road will bond firmly.

In the actual construction, some construction units use the oil of the cloth to spread Fiberglass gratings directly, the roller compaction is followed by the roller, the effect is better, and the Fiberglass gratings is not easy to wrinkle.
In the actual operation, the quality of the construction has a great influence on the use of Fiberglass gratings in the future.
