2.5mm D49 High Tensile Steel Reinforcement Wrapping Mesh 2400mm x 4800mm

Product Overview

D49 light-duty welded steel fabric used as reinforcement in cementitious screeds. 

Each sheet consists of cold-reduced steel wires, 2.5mm in diameter, resistance welded at 100mm centres to form a square grid pattern.

When laid within screeds, the mesh improves tensile strength and helps control shrinkage cracking during the drying and curing process. 

It also minimises curling at edges and joints, ensuring a more stable, durable surface.

Because it is thinner and lighter than heavy-duty reinforcement mesh, D49 is easy to handle and cut to size on site. 

It is widely used in residential and light commercial projects, particularly where screed thickness is limited.

Features & Benefits

• Lightweight 2.5mm wire gauge: Easy to handle, cut, and place on site without heavy equipment.
• 100mm × 100mm mesh spacing: Provides uniform stress distribution across the screed.
• Resistance-welded joints: Maintains grid stability under load and prevents displacement.
• Controls shrinkage cracking: Reinforces screed against movement during curing.
• Reduces curling at edges and bays: Keeps screed surfaces level and reduces remedial work.
• Improves tensile and flexural strength: Increases screed performance under load and bending stress.
• Conforms to BS 448: Meets industry standard for welded steel fabric reinforcement.
• Cost-effective reinforcement: Lighter than heavy-duty mesh, making it economical for domestic and light-use floors.
  
  

Applications

• Unbonded screeds on membranes: Reinforces screeds separated from the slab with a slip layer, reducing curling and cracking.
• Floating screeds over insulation: Adds strength where screeds are laid on thermal or acoustic insulation layers.
• Bonded screeds on concrete bases: Enhances adhesion and durability where screed is directly bonded to the substrate.
• Small concrete slabs or bays: Helps control shrinkage cracking where joint spacing is limited.
  
  

Installation Guidance

• Position mesh at mid-depth of screed layer: Ensures reinforcement is effective in resisting tensile stresses.
• Overlap adjoining sheets by at least 100mm: Maintains continuity of reinforcement across the floor area.
• Use chairs, spacers, or broken tile supports: Prevents mesh from sagging to the base, ensuring correct cover within the screed.
  
  

Compliance & Performance

• Manufactured to BS 448 and CARES approved: Verified against UK standards for steel reinforcement products.
• Resistance-welded steel fabric: Provides consistent mechanical properties and quality assurance.
