Formwork Beams BT20, BT20 ECO and SmartBeamPlus – Which Model Should You Choose? A Guide for Contractors
BT20 Formwork Beams – How to Choose the Right Model for Your Construction Project?
Formwork beams are one of the key components used when constructing concrete slabs and walls. They transfer loads and maintain the stability of the entire system, so choosing the right model has a significant impact on worksite safety and the pace of project completion.
At Szaluj.pl, we offer three key models that differ in design, strength and intended use:
- BT20 ECO beam – a lightweight, economical design, ideal for less demanding applications.
- BT20 beam – a classic, highly versatile model compatible with most formwork systems.
- BT20 Premium / SmartBeamPlus beam – a reinforced version with full end fittings, designed for intensive use and heavy loads.
The comparison below will help you quickly determine which model is best suited to your construction project.
Why Are Timber Formwork Beams So Popular?
Timber formwork beams are valued primarily for their:
- excellent strength-to-weight ratio,
- easy transport and quick installation,
- compatibility with most formwork systems,
- reusability,
- ability to withstand loads in both vertical and horizontal applications.
Their flanges and web design allows them to transfer both line and point loads while maintaining the stability of the formwork and ensuring the safety of workers on site.
