How much does waterproof metal wall cladding cost per m²?

Factors affecting the cost of waterproof metal wall cladding

The cost of waterproof metal wall cladding varies depending on materials, thickness, scale, and construction conditions. Understanding these factors helps you determine fair pricing and avoid overquoting.

Type of metal sheet

Common types of waterproof metal sheets include:

• Cold-rolled sheets: 115,000-135,000 VND/m²; durable, lightweight, ideal for townhouses.
• Dong A sheets: 125,000-145,000 VND/m²; rust-resistant and weatherproof.
• Hoa Sen sheets: 130,000-150,000 VND/m²; premium quality, glossy surface, lifespan up to 15 years.
• PU insulated sheets: 150,000-180,000 VND/m²; excellent heat and sound insulation.

Thickness and construction area

Thicker sheets (3.5-4 zem) provide better waterproofing and durability but increase cost by 5-10%. For large areas above 50 m², average prices decrease by 5-10% due to bulk material and labor discounts.

Construction location

Projects on high walls or narrow alleys cost slightly more due to scaffolding and safety gear requirements. Conversely, ground-level or low-wall projects are 10-15% cheaper.

How to calculate waterproof metal cladding cost by area

Many clients wonder why quotes differ for the same sheet type. In reality, total cost depends on three main factors:

1. Material cost

Accounts for 60-70% of total price. For example, Hoa Sen 4-zem sheets (150,000 VND/m²) include sealant, screws, and protective coating.

2. Labor cost

Average 60,000-80,000 VND/m², depending on wall height and complexity. SKSumo’s quoted prices already include labor - no extra charge.

3. Additional costs

Includes transportation, cleaning, and support framing: about 10,000-25,000 VND/m².

Examples:

• 20 m² wall using Dong A 3.5-zem (135,000 VND/m²) → Total = 135,000 × 20 = 2,700,000 VND
• 60 m² wall using Hoa Sen 4-zem (150,000 VND/m²) with 10% discount → Total = 150,000 × 60 × 0.9 = 8,100,000 VND

FAQs about waterproof metal wall cladding

Should waterproof metal sheets be installed vertically or horizontally for best results?

Install vertically from roof to ground for faster rain drainage and fewer seam leaks - extending sheet lifespan by 20-30% compared to horizontal installation.

How to identify genuine waterproof metal sheets?

Authentic sheets have embossed brand logos (Hoa Sen, Dong A, Hoa Phat) and lot codes printed on the underside. Request factory invoices or CO-CQ certificates to avoid counterfeits.

Should the steel frame be treated before installation?

Absolutely. Apply two coats of anti-rust primer before installation to prevent oxidation. This step reduces 70% of reverse seepage and rust risks over 3-5 years.

When should old waterproof cladding be replaced?

After 10-12 years, if fading, peeling, or minor leaks appear along seams. Regular inspection helps save 30-40% compared to full replacement.

Can waterproof cladding be combined with thermal insulation?

Yes. PU or 3-layer EPS-insulated sheets enhance heat and sound insulation while maintaining waterproof performance. Though 15-20% costlier, they offer superior longevity and comfort.
