EN 13374 Temporary Edge Protection Guide: Class A, B & C Roof Slope Limits, Impact Energy & Post Selection
Preventing falls from open concrete slabs and roofs requires collective barriers engineered to EN 13374—which categorizes systems into Class A, Class B, and Class C according to working surface slope and kinetic arrest energy.
| EN 13374 Class | Max Surface Slope | Primary Load Test | Typical Construction Application |
|---|---|---|---|
| Class A | 0° to 10° Flat Slabs | Static Point Loads (0.30–1.25 kN) | Concrete Floor Perimeters, Balconies, Elevator Shafts, Stairs |
| Class B | 10° to 30° Pitched Surfaces | Static + 1,100 J Dynamic Pendulum Impact | Low-to-Medium Pitch Commercial & Residential Roofs |
| Class C | 30° to 45° Steep Roofs | 2,200 J High-Velocity Kinetic Arrest Test | Steep Pitched Roofs & High Sliding Energy Zones |
1. Why EN 13374 Class A Mesh Panels Dominate Multi-Story Concrete Construction
Flat concrete floor slabs, balconies, and elevator cores fall under Class A (<10° slope). SerMimar SM-K532 panels (105×250 cm) integrate top guardrail, welded steel mesh infill, and a 15 cm solid steel toeboard in one rigid unit.
2. Matching the Right Post to Formwork, Post-Tensioned Slabs & Stairwells
Combine standard SM-K532 barriers with SM-K506 non-drilling slab clamps, SM-K501 bolt-down posts, SM-K511 timber formwork clamps, or SM-K553 stair stringer brackets.
