Shuttering Materials: Durable and Reliable Solutions for Construction
Shuttering (vertical formwork) shapes and supports wet concrete until it cures. At Avanza Steel, our shuttering materials combine precision steel fabrication with durable plywood systems, ensuring perfect concrete finishes, faster cycle times, and reliable on-site performance.
What Is Shuttering?
Shuttering, or formwork, provides a temporary mold for vertical concrete elements (walls, columns, beams), holding wet concrete until it hardens into the desired shape. Proper shuttering ensures dimensional accuracy, surface quality, and structural integrity.
Why Avanza Steel Shuttering?
-
Precision & Durability: Steel plates and frames resist deflection under high pressure, outperforming timber in longevity.
-
Speed & Reusability: Modular panels and engineered accessories (tie rods, anchor bolts) streamline assembly/disassembly, reducing labor costs.
-
Surface Finish: Smooth steel and phenolic-coated plywood deliver near-perfect concrete surfaces, minimizing remedial work.

Production capacity of 5,000+ Cuplock uprights per month ensures large-scale projects stay on schedule—whether you’re in Kolkata, Delhi NCR, or the Middle East.
Installation & Best Practices
-
Panel Layout
-
Start at one corner, align steel shuttering plates vertically, and interlock edges before tightening tie rods.
-
-
Tie-Rod Tensioning
-
Pre-tension tie rods to design load (check torque specs in brochure) before concrete pour to prevent bulging.
-
-
Alignment & Leveling
-
Use spirit levels on column forms; adjust via prop sleeves to maintain plumb within ± 2 mm.
-
-
Release & Cleaning
-
Remove panels once concrete reaches 70% of design strength; clean steel and plywood surfaces immediately to extend service life.
