Aluminum formwork systems have become a go-to solution for high-rise buildings and large-scale concrete structures due to their light weight, high strength, fast cycle times, and excellent reusability. But choosing the right formwork system isn’t just about the price. Before placing an order, here are 5 essential factors to evaluate to ensure the best return on your investment:
1️⃣ Material Grade & Wall Thickness
High-quality formwork is typically made of 6061-T6 or 6063-T6 aluminum alloy, known for their strength and corrosion resistance. The ideal wall thickness is between 4mm–6mm. Anything thinner may deform during use, while thicker material increases unnecessary cost and weight.
✅ Tip: Ask for a material report and check alloy specifications and thickness tolerances.
2️⃣ Precision & Panel Fit
Beyond raw material, assembly accuracy is key. Poor tolerance in bolt holes or panel joints can result in leakage, misalignment, and inefficient site work.
✅ Tip: Request an in-person mockup or panel sample. Ensure connection gaps are ≤ 2mm.
3️⃣ Surface Treatment
Aluminum formwork should be surface-treated via anodizing, electrophoresis, or powder coating to prevent corrosion and reduce concrete adhesion.
✅ Tip: Choose products with smooth, uniform surface treatment to ensure long-lasting performance and fewer on-site cleaning issues.
4️⃣ System Completeness & Design Service
A reliable supplier should offer a complete system, including wall panels, slab panels, beams, corners, props, and accessories. More importantly, they should provide project-specific design support, BOQ matching, and field guidance.
✅ Tip: Select suppliers that offer end-to-end service, from drawing optimization to installation consultation.
5️⃣ Reusability & Service Life
This is the core value of aluminum formwork. A good system should allow for 200+ reuse cycles, while high-performance systems can exceed 300 times. Cheaper alternatives with limited lifespans may cost you more in the long run.
✅ Tip: Ask for reuse data and real case references from similar projects.
