Product Introduction

Key Value Propositions

& Differentiators

Reduced structural mass

slim, cold-formed steel profiles reduce foundation loads & material cost.

Fast, modular assembly

factory-prefabricated components; bolt-together assemblies; quicker site erection.

Energy & cost efficiency

less material waste; improved insulation; reduced labor and transport cost.

High strength in lightweight form

steel grades & design enabling good load-bearing despite lighter components.

Flexibility & adaptability

modular spans, multi-story possibilities, mixed usage.

Sustainability & durability

steel is recyclable; resistance to weather, pests, fire.

Use Cases

Small to medium warehouses, storage & logistic buildings
Commercial buildings: shops, offices, exhibition halls
Residential / multi-family housing where lightweight framing preferred
Agricultural buildings: poultry houses, farm sheds, cold storage etc.
Low-rise institutional buildings: community centers, schools in remote or cost-sensitive zones

Technical Specifications & Design Parameters

Parameter	Typical / Offered Range or Example	Why It Matters to Buyer
Steel Material / Grade	Cold-formed steel: grades equivalent to Q235 / Q355 (or S235 / S355), or local standard. Steel thickness typically in the range of 0.8 mm to ~3 mm for cold-formed members in lightweight systems.	Affects strength, durability, weight, cost, ease of transport.
Span / Clear Width	Single-span or multi-span layouts; clear spans up to 30-36 m using lightweight profiles in some designs. Smaller spans (~6-15 m) typical for many lightweight structures.	Larger span reduces number of internal supports, giving more open interior space, but requires stronger members or more bracing.
Height (Eave / Ridge)	Eave heights typically between 3 m to 10-12 m depending on usage (warehouse height, mezzanine, etc.). Roof pitch/slopes variable depending on climate & drainage.	Determines clearance, internal usability, drainage, cost of roofing/cladding.
Roof & Wall Cladding & Insulation	Options include single steel sheet panels, insulated sandwich panels with PU / EPS / Rock-Wool / Glass-Wool cores; panel thickness from ~50 mm to 150 mm (or more) for heavy insulation zones. Panel coating options (pre-painted, PVDF, HDP, SMP) or hot-dip galvanizing.	Affects thermal comfort, energy use, weather resistance, sound insulation, appearance.
Secondary Framing	C-section or Z-section purlins/girts; sizes from e.g. C80~C300 / Z100~Z300 in many prefabs. Bracing (X, V or knee braces) to ensure lateral stability.	Provides rigidity, resists wind/snow loads, ensures panel support, reduces deflection.
Load Capacities	Design for snow loads, wind loads, seismic loads per local code; live loads (maintenance, storage) plus dead loads (structure, panels). Examples: span loads of 350-500 kg/m² possible in some designs.	Must meet safety & regulatory standards; influences member sizing and cost; critical to determine required strength.
Connection & Assembly	High strength bolts, self-tapping screws, welded joints in some parts; design for ease of connection & minimal welding on site. Prefab, shop drilling.	Affects erection speed, quality control, field reliability.
Foundation & Anchoring	Pad or strip concrete footings; anchor bolts; base plates; likely lighter foundation requirements due to lower structural weight. Soil bearing capacity matters.	Reduces foundation cost; essential for ensuring structure stability and integrity, especially under dynamic loads.
Corrosion Protection & Finishing	Hot-dip galvanizing; pre-painted steel; coatings suitable for UV, moisture; thicker coatings or special paints for coastal or humid regions.	Ensures longevity, reduces maintenance, prevents corrosion in tough climates.
Fire & Safety Features	Non-combustible materials; possibility of fire rating for walls/roof; emergency escapes; ventilation; compliance with local safety/fire code.	Critical for regulatory approval and occupant safety.

Manufacturing, Quality Assurance & Testing

Factory prefabrication under controlled conditions: roll forming, cutting, punching.
Mill test certificates for steel materials.
Coating / paint quality assurance: thickness, adhesion, salt spray / corrosion testing.
Structural module fitting tests (e.g., check bolt holes, alignment).
Performance tests: thermal insulation, sound insulation; under load deflection tests; wind & snow load calculations.
