Whether it’s a private residence, commercial carwash, or industrial facility heavy duty (HD) fiberglass grating has become the most suitable primary structural material due to the superior load capacity, impact resistance and excellent corrosion resistance in harsh environments. Mach’s heavy duty fiberglass grating is strong enough to withstand vehicular loads in a wide array of industries. It can load from transport trucks (H-20) and forklifts and will never warp/rust/corrode and become unsafe, which provides the most durable and lowest maintenance solution in harsh environments!

Our HD fiberglass grating is available in molded and pultruded options to suit all kinds of applications, for example, our heavy duty square mesh is also ideally used as the floor for adult cattle. No more safety hazards and high maintenance costs caused by warped steel gratings, please feel free to consider our heavy duty fiberglass grating!

Custom products, we are able to manufacture all kinds of heavy duty fiberglass grating as you required!

Q1: How do you ensure the quality of FRP products?

A: All products are manufactured in our own factory under strict ISO-based quality control. We perform raw material testing, process monitoring, and final inspection to ensure every panel meets strength, durability, and corrosion-resistance requirements.

Q2: Where can FRP products be used?

FRP products are ideal for chemical plants, wastewater facilities, offshore platforms, walkways, platforms, stairs, and other areas that require corrosion resistance, lightweight structure, and long service life.

Q3: Do you provide after-sales support?

Yes. We provide clear documentation, installation guidelines (if needed), and technical support. If any quality issue is confirmed after delivery, we offer replacement, rework, or other agreed solutions.

Q4: Can you help with project-specific requirements?

Absolutely. Our team can suggest the right resin system, grating type, and surface finish for your application, and provide drawings or design assistance to ensure project success.
