Engineered High-Strength Aluminum Alloy Cast-in-Place Concrete Panel System Formwork

An aluminum formwork system is a reusable construction system used to cast concrete walls, slabs, beams, columns, stairs, and other structural elements. It combines lightweight aluminum panels with supports, connectors, braces, ties, and accessories to create an accurate concrete mold. ELPHA aluminum formwork systems can be engineered around a project's architectural and structural drawings.

The principal advantages of aluminum formwork are fast construction, consistent dimensions, smooth concrete finishes, reduced dependence on heavy lifting equipment, and high reuse potential. Because the panels are lightweight and precision-manufactured, construction teams can achieve repeatable results across residential, commercial, and infrastructure projects.

A complete aluminum formwork system may include wall panels, slab panels, beam panels, internal and external corners, K-boards, props, walers, diagonal braces, pins, wedges, bolts, flat ties or tie rods, wing nuts, clamps, and early-stripping accessories. ELPHA determines the final component schedule from the project drawings and selected reinforcement method.

High-quality aluminum formwork panels are commonly manufactured from 6061-T6 aluminum alloy. The referenced technical specification lists tensile strength of at least 260 N/mm, yield strength of at least 240 N/mm, and density of approximately 2,700 kg/m. This alloy provides a useful combination of strength, low weight, corrosion resistance, and dimensional stability.

Aluminum formwork is suitable for high-rise apartments, residential developments, hotels, office buildings, villas, basements, commercial buildings, and selected infrastructure projects. It delivers the greatest economic benefit on projects with repetitive floor plans, standardized structural dimensions, and multiple concrete-pouring cycles.
