High-Load Primary & Secondary Slab Beams
Heavy-bending aluminum and wood-composite H20 beams configured for flexible horizontal deck layout structures.
Aluminum H140 vs Wood H20 Beams
Slabform designs and stocks high-moment secondary and primary support beams. Our Al-Beam H140 (140mm height) provides more than twice the bending strength of a traditional timber H20 girder while eliminating common wood failures like splitting, rot, and localized crushing at load interfaces. When used as primary supports (girders) and secondary supports (joists), these beams carry massive dynamic hydrostatic loads over wider spans, drastically reducing the total count of vertical shoring props required.
Beam Load Comparisons and Bending Moments
The selection of beam sizes determines physical support spans. Below are calculated physical properties of our beam systems:
| Beam Type & Height | Material Formulation | Bending Stiffness (EI) | Permissible Bending Moment (M) |
|---|---|---|---|
| Alu-Beam 140 (14cm) | Aluminum Alloy 6082-T6 | 450 kNm² | 14.5 kNm |
| H20 Timber (20cm) | Spruce with Polyurea nose protection | 45 kNm² | 5.0 kNm |
| Steel C-Profile 120 | Hot-dip Galvanized High Tensile | 310 kNm² | 11.0 kNm |
Continuous Splitting Guard & Screw Tracks
Our Alu-Beam 140 profile features a dedicated, integrated continuous synthetic timber slot along the top face. This allows carpenters to quickly anchor plywood overlays or edge curbs with standard dry-wall screws without drilling directly into the primary structural aluminum framing. The bottom groove is optimized to anchor standard prop head adapters with zero sliding potential.
