The grid of sewage treatment plants has flexible plasticity. Various specifications, sizes, and colors of grille products can be customized according to usage and environmental requirements. So, what are the common colors of the grille in sewage treatment plants? Below, the editor will guide you one by one.

The commonly used colors for the grille of sewage treatment plants include red, yellow, green, black, and gray. These colors are determined by the color and quantity of pigments added during the production process. The amount of pigment added is generally 1% to 5% of the resin mass. In the production of fiberglass grating, different pigments have accelerating and inhibiting effects on the curing of unsaturated polyester resin. Therefore, when choosing pigment paste, attention should be paid to their impact on the curing speed of the resin.
In addition, the color of the grille of the sewage treatment plant can be customized according to the specific requirements of the customer. Common color types include yellow, red, blue, green, gray, dark gray, transparent, and so on. Among them, transparent type grille panels refer to those made of pure resin without adding color paste. Its color is bright and long-lasting, uniform inside and outside, does not require painting, has a bright color, and can improve the environment of the production site. The cleaning process is also very simple, just rinse with clean water.

The color of the grille in sewage treatment plants is not just a layer on the surface, but is made by blending color paste into all resins, which has the characteristics of diverse colors, uniform coloring, and not easy fading. It won’t fade when used indoors all year round, but it’s different outdoors. The color will fade to some extent after being exposed to sunlight all year round, but it doesn’t affect the normal use of fiberglass trench covers. The only difference is that the color of the cover is not as bright. High quality covers will also fade slightly within 2 years, while low-quality covers can fade within a few months. If the grille of the sewage treatment plant is exposed to sunlight outdoors all year round, gray can be chosen as the color, so there is no significant difference; Alternatively, depending on the intended use, patterned cover plates can be added outdoors all year round to increase strength and resist UV rays.
What are the commonly used colors for the grille of sewage treatment plants? After introduction, in addition to bright colors, FRP trench covers also have the advantages of acid and alkali resistance, aging resistance, insulation, high load bearing, bright colors, long service life, etc., which are widely used in various industries.
