Light Steel Structure House

 

High industrialization and prefabrication: modules, pre-punched steel members; rapid on-site assembly.

Lightweight yet strong: reduced foundation loads; excellent seismic & wind performance.

Energy efficiency and comfort: high insulation, moisture control, minimal thermal bridging.

Durable finishes and corrosion protection for harsh climates (coastal, rainy, humid).

Flexibility in design: multiple floors, varied layouts, customizable openings, finishes.

Sustainability: recycled materials; lower carbon footprint; dry construction; faster build cycles.

 

 

Below are typical specifications you should provide or ensure are met. These are what B-2-B buyers will often require.

Parameter	Typical / Offered Range	What Buyer Needs to Know & Why
Steel Grade / Profiles	Cold-formed thin steel keel / C / Z profiles; thickness may be ~0.8-1.5 mm (for walls/roof purlins), or heavier where needed. Steel yield strength e.g. ≥ Q355, or equivalent ASTM / AISI grade.	Determines structural strength, deflection, durability.
Frame Members Spacing & Layout	Stud / column spacing often 400-600 mm or as per local code; purlin spacing depending on roof load (e.g. ≤ 1.0-1.2 m for high snow).	Affects load capacity, insulation, cladding support, and cost.
Insulation / Thermal Performance	Wall and roof insulation: glass wool / rock wool / XPS / EPS sandwich panels; thickness in the range 90-200 mm depending on climate; thermal conductivity ~0.030-0.045 W/(m·K).	Ensures occupant comfort, energy efficiency, compliance with local energy codes.
Live Loads / Dead Loads	Floor live load (e.g. ≥ 200 kg/m² or more for residential); roof snow load based on local snow height (e.g. 150-300 kg/m² or higher in cold/snowy regions); dead loads from roof panel, cladding, insulation.	Buyers must plan for loads according to local code to avoid failure/collapse; affects member sizing.
Wind & Seismic Design	Designed to resist typhoon / high wind zones (e.g. wind pressure ≥ 0.6-1.0 kN/m² in coastal regions); seismic zone compliance (local equivalent of magnitude 7-9, or -g acceleration).	Safety, code compliance, insurance, durability.
Roof Design	Roof slope (single or double slope), roof panel options (metal, tile, asphalt shingle, sandwich panel), waterproofing layers, OSB or structural sheathing beneath. Snow accumulation control where relevant.	Necessary for weather tightness, durability, structural performance.
Wall / Cladding Systems	Composite sandwich panels, fiber cement boards, decorative panels; moisture barrier, vapour control; interior finishes (gypsum board etc.).	Should provide durability, appearance, indoor environment quality.
Doors & Windows / Openings	Customizable sizes; well-sealed aluminum or steel doors; double glazing, thermal break frames; security and safety considerations.	Functionality, safety, thermal and acoustic performance.
Foundations & Anchoring	Suitable foundations for light steel frame: concrete strip footings, pad footings, ground screws (if appropriate). Anchor bolts base plates; ensure level, frost protection.	Correct foundation avoids differential settlement, ensures structural integrity.
Corrosion Protection & Finish	Hot-dip galvanizing, zinc or aluminum-zinc coating, optionally powder-coat or PVDF, real stone paint, or weather resistant coatings; recommend higher coating weights for coastal/humid zones.	Longevity, less maintenance, resisting rust / salt / moisture.
Service Life / Durability	50 years or more under proper maintenance; designed for regional environmental conditions (sun, moisture, temperature cycles).	B2B buyers budget for lifecycle cost, not just upfront cost.

 

 

 

 

• Material certificates for steel (grade, tensile & yield strengths, coating weights).

• Factory fabrication: pre-punching, precision cutting, pre-assembly, tolerance control.

• Assembly QA: alignment, straightness of members, connection strength (bolts/screws/welds).

• Insulation, waterproofing, cladding QA: moisture barrier testing, leakage, thermal bridging checks.

• Environmental and structural testing: wind uplift, snow load, acoustic and thermal performance (if applicable).

 

• Coating options: galvanized steel (HDG), zinc/aluminum alloy plating, optional powder coat or PVDF topcoat.

• Paint / cladding materials chosen for UV resistance, moisture control, salt spray resistance.

• Roof overhangs, drip edges, gutter design to prevent water penetration.

• Ventilation / moisture barriers to avoid condensation and corrosion inside wall cavities.

 

These are the items procurement managers should verify before purchase/supply:

Required clear span widths, number of storeys, floor heights.

Local design parameters: wind speed, snow load, seismic zone.

Foundation soil conditions and site constraints.

Thermal & insulation requirements; internal living comfort expectations.

Finish & cladding performance (corrosion, moisture, UV).

Doors/windows specifications and sealing.

Energy / sustainability certifications if needed.

Warranty terms, maintenance support, spare parts.

Local code compliance and engineer drawings / permits.
