Guangdong Haikuo is a leading manufacturer of pultruded and molded grating, with over 20 years of experience designing and manufacturing these products. We offer a wide range of grating to suit a variety of applications.
Pultruded Grating
Pultruded grating is made through pultrusion — a process that pulls a continuous fiber-reinforced resin composite through a heated die, producing a strong, lightweight, corrosion-resistant grating.
Advantages of Pultruded Grating
Strong and durable: pultruded grating is stronger and more durable than molded grating, since its fibers align in the load direction for greater strength.
Corrosion-resistant: holds up well in harsh environments.
Lightweight: significantly lighter than molded grating, easing transport and installation.
Customizable: size, shape, and material can all be tailored to specific requirements.
Disadvantages of Pultruded Grating
More expensive: pultruded grating typically costs more than molded grating.
Limited design options: shapes and sizes are more constrained than with molded grating.
Molded Grating
Molded grating is made by pouring resin into a mold and curing it — a process that produces grating that’s strong, durable, and cost-effective.
Advantages of Molded Grating
Cost-effective: molded grating typically costs less than pultruded grating.
Wide range of designs: available in many shapes, sizes, and materials.
Easy to install: simpler to install than pultruded grating.
Disadvantages of Molded Grating
Not as strong: molded grating falls short of pultruded grating in strength, since its fibers aren’t aligned with the load direction.
Not as corrosion-resistant: less resistant than pultruded grating.
More maintenance: the resin is more susceptible to damage, so it needs more upkeep.
Which Type of Grating Is Right for You?
The best grating for your project depends on your specific needs. If you need strength, durability, and corrosion resistance, pultruded grating is the better choice. If you need a cost-effective option with a wide range of design choices, molded grating fits better.
A few factors to weigh when choosing between the two:
Strength: for heavy loads, pultruded grating wins out.
Corrosion resistance: for harsh environments, pultruded grating is the safer bet. Cost: on a tight budget, molded grating is more economical.
Design options: if you need a specific look, molded grating offers more flexibility.
