1. Preventing Gate Sagging with Structural Steel Sections

Cheap local fabricators often use thin 1.2mm hollow pipes that bend and sag under the weight of the gate over time. Sparsh Trading utilizes 2.5mm to 3.0mm heavy Tata Structura rectangular sections and heavy industrial ball-bearing pivot hinges that ensure effortless swinging for decades.

2. CNC Fiber Laser Cutting Technology

High-power fiber laser cutting cuts intricate 3mm-5mm steel sheets with clean, burr-free edges and tight geometric accuracy, creating stunning geometric and floral jaali panels.

3. Multi-Layer Anti-Rust Primer & PU Coating

To withstand harsh weather, every gate is treated with 2 coats of zinc chromate red oxide epoxy primer followed by automotive-grade polyurethane (PU) topcoat enamel.
