S-pida specializes in wooden R-shaped formwork designed for curved structures. These formwork panels are used in various construction sites requiring sophisticated design, such as civil engineering and architectural projects. The curved plywood is pressed into shape to meet project specifications and can be easily cut with saws or planes. In infrastructure and urban development projects, it supports the construction of structures that are not only functional as formwork but also aesthetically pleasing and do not obstruct the landscape or natural environment.
 
S-pida offers a variety of services that flexibly meet customer needs, primarily focusing on concrete formwork for civil engineering and construction. They use plywood and timber from tropical hardwoods, as well as LVL (Laminated Veneer Lumber), MDF (Medium-Density Fiberboard), and engineered wood products, aiming to protect limited forest resources. They offer a wide range of products such as curved plywood, circular and irregular formwork for civil engineering and construction, PC (precast concrete) formwork, and panel formwork with battens. Their in-house R-shaped formwork factory handles everything from pressing to shipping in a streamlined process.
S-pida’s integrated production system allows them to offer custom-made formwork in any shape or size. Utilizing CAD/CAM systems and NC woodworking machines, they provide high-quality, uniform, and cost-effective concrete formwork. Their manufacturing technology reflects various designs and specifications from construction sites nationwide, ensuring both functionality and innovative design.
S-pida’s civil engineering formwork includes R-type haunches, spheres, double curves, transitions from round to square, boat bottoms, and wave barriers. Applicable structures include piers, bridges, dams, harbors, revetments, water treatment plants, railways, tunnels, and waste disposal facilities. For architectural concrete formwork, they have completed projects involving round columns, S-shaped walls, spiral staircases, elliptical domes, monuments, conical walls, and slabs. These formworks are applied in hotels, office buildings, commercial facilities, apartments, schools, and libraries.
Wooden formwork, like the R-shaped formwork offered by S-pida, is easy to process and suitable for curved concrete structures. It is lightweight and easy to handle but generates waste. System formwork, on the other hand, is easy to assemble, highly reusable, and significantly reduces labor and costs. Combining wooden formwork with system formwork according to the site can improve work efficiency, reduce costs, and shorten construction time.
We have selected formwork manufacturers from 55 companies found through a Google search for 'formwork panel manufacturers' as of February 1, 2022. The selection is based on the following criteria:
Based on construction examples, we have assessed the the number of construction cases handled, and categorized them into residential, commercial buildings, and civil engineering. We recommend those that simplify the installation process the most.
