Brick Mesh Wall: Stronger, Crack-Free Walls - Why Choose Us?

If you’re weighing reinforcement options for a brick mesh wall, you’ve probably noticed the market has quietly shifted in the last two years—toward smarter galvanizing, tighter tolerances, and more predictable crack control. I’ve toured a few lines, talked to jobsite supers, and yes, kicked a couple of pallets in the yard. Here’s the distilled view.

What it is and why it’s trending

Brick mesh (often called brick force) is narrow coil reinforcement embedded in bed joints to control shrinkage and thermal movement. Today’s demand is driven by façade warranties, seismic detailing, and the frankly relentless need to keep hairline cracking off punch lists. The Chengsen “Galvanized Expanded Wire Mesh Metal Brick Force Mesh Coil Mesh,” made in Shijiazhuang, China, is a representative example of the new generation—clean expansion cuts, consistent strand width, and coating options that match environment, not guesswork.

Two common styles (and when to use each)

• Expanded metal brick mesh: slit-and-stretched sheet; no welds; great bond and continuity.
• Welded brick force: parallel wires spot-welded to cross wires; very linear, easy lap control.

On most brick mesh wall jobs, expanded metal wins for adhesion in mortar; welded is handy when the spec calls out exact wire diameters. Many customers say expanded coils feel “stickier” in the joint—less slippage when tooling.

Typical specs (field-proven, not just brochure promises)

Process and quality flow (short version)

Materials come in as slit coils, then expanding/flattening, optional hot-dip or electro-galvanizing, passivation, and coil re-wind. Testing: zinc weight per ASTM A90/A90M, wire chemistry, tensile, and salt-spray per ASTM B117. Batches are sampled to EN 845-3 dimensional tolerances. Honestly, the fastest way to spot quality is consistent strand width once flattened.

Application scenarios

• Brick mesh wall crack control in long runs and openings.
• Seismic and wind-load regions where bed-joint reinforcement is specified.
• Cavity walls, veneer ties, lintel zones, and facade retrofits.
• Plaster/stucco backing over masonry (select patterns).

Case notes and feedback

A coastal school project I tracked specified HDG 150 mm expanded mesh at every third course. After 1,000 hours of ASTM B117 lab testing, the zinc loss trend aligned with the spec’s 20-year maintenance curve. Site foreman’s words, not mine: “No curl, no fight—coils laid flat, saved us half a day.” On a hospital retrofit, welded brick force was chosen instead for strict wire-size compliance; both met crack-control targets, but expanded bonded better in high-suction mortar.

How to specify (to be safe, not sorry)

• Type: expanded or welded for your brick mesh wall.
• Width and lap: match brick unit + joint (common 100 or 150 mm; ≥150 mm laps).
• Coating: exterior/coastal → HDG ≥ Z275; interior dry → electro acceptable.
• Call out compliance: EN 845-3; wire to ASTM A1064; zinc to ASTM A641 or ISO 1461.
• Ask for salt-spray data and coating weight test reports.

To be honest, the cheapest coil isn’t cheaper if it curls or clogs joints. Look for consistent apertures, decent packaging, and traceable test slips.
