Product Technical Specifications

Why Choose Our 4-Hole Hollow Large Grille?

Engineered for Large-Scale Applications

Your project demands materials that perform in challenging environments. Our product is specifically designed for expansive wall installations in shopping malls, transportation terminals, and industrial offices across Africa, Asia, and the Middle East.

The straight-through hole design prevents debris accumulation in sandy or dusty environments. Wind naturally clears sand particles, eliminating maintenance concerns common in desert regions.

Superior Material Efficiency

The hollow architecture reduces material consumption by approximately 30% without compromising strength. This translates to lower product costs for you while maintaining durability.

Lighter weight means more pieces fit per shipping container. You'll reduce freight expenses while accelerating project timelines.

Flexible Customization Options

Need specific dimensions? Our factory cuts profiles to any length up to 3m. Choose from WPC for outdoor UV resistance or PVC for interior applications.

Request custom colors to match your design vision. We offer wood grain, solid colors, and textured finishes through our extensive surface treatment capabilities.

FAQ

Q: How much material does the hollow design save?

A: About 30% less material compared to solid profiles—directly lowering your product cost while reducing environmental impact.

Q: Will sand accumulate inside the holes in desert areas?

A: No. Holes are straight through from front to back. Sand blows out naturally with wind, preventing clogging and eliminating maintenance requirements.

Q: Can this be installed outdoors?

A: Aluminum versions perform excellently outdoors. WPC versions require UV stabilizer additives for exterior use, available through custom order specifications.

Q: What is the maximum length you can produce?

A: We customize lengths up to 3m. Standard stock length is 2.44m for immediate availability and cost efficiency.

Q: Do you offer bulk discounts?

A: Yes. Volume orders qualify for preferential pricing. Contact our team for project-specific quotations based on your total square meter requirements.

Q: How is the product packaged for export?

A: Each order receives professional export bundling with pallet reinforcement. This protects profiles during ocean freight and rough handling in port facilities.
