Wood and steel Custom formwork
Larger size custom formworks in wood or steel require a certain amount of preparation; these are generally planned with state of the art CAD systems, manufactured to specifications at steel construction or carpentry companies, and undergo a trial set-up, where required. On site, this would not be an option, as time, space, experts, and required facilities are at a premium. Building contractors increasingly rely on their formwork supplier to manufacture custom formworks, as they have no space at the building site or at their own facilities to produce of this type formwork.
PASCHAL’s custom formworks division provides a professional ready-to-use service for custom formwork.
The critical factor for the use of wood or steel in custom formworks is generally the number of required uses, and the required surface finish of the concrete. Where the main concern is longevity and a high number of deployments, the more expensive steel version is often the more cost-effective solution, than the lowercost wood design, which would have to be manufactured with more iterations. Wood is therefore the material of choice, where formworks will only used a few times. When using wood, or various wood blanks, it is often easier to achieve certain surface structures, particularly if these are to be variously profiled or otherwise structured, instead of having a smooth finish.
Wood and steel can however also be combined, e.g. where an existing steel frame formwork is used as support structure to support facing plywood.
