China Prefab Multi Storey Precast Apartment Buildings Manufacturer

Specifications & Compliance

Reference specs for our Steel Structure Warehouse Building platforms. Custom configurations available — these are starting points, not limits.

China-Based Prefab Apartment Building Manufacturer with Full EPC Capability

We’re a vertically integrated China-based prefab apartment building manufacturer — not a trading company or middleman. Since 2001, we’ve delivered over 1,200 multi-storey precast residential projects across 52 countries. As an EPC provider, we own design, steel fabrication, panel production, logistics, and on-site supervision — all under one roof.

• Full control from blueprint to handover: No subcontractor delays, no quality gaps between design and execution.
• 48,000 m² smart manufacturing base: Daily output capacity of 5,000 m² ensures stable lead times even for orders above 10,000 m².
• ISO 9001 / ISO 14001 / ISO 45001 certified: Six-step in-process quality control, traceable raw material sourcing (Q345B/Q235B steel), and third-party SGS/CE/AS/NZS verification included.
• Belt and Road infrastructure experience: Proven track record in seismic zones (up to Grade 9), high-wind regions (max. 65 m/s), and cold climates (–30°C).

Prefabricated Multi-Storey Apartment Buildings Engineered for Speed & Compliance

Our prefab multi-storey apartment buildings are designed for rapid deployment without compromising structural integrity or regulatory compliance. Typical delivery: 31–45 days after final drawing approval. Projects up to 12 storeys are engineered per local codes — including AS/NZS 1170, Eurocode EN 1991, and IBC 2021.

• Turnkey timeline reduction: 60% faster than cast-in-place construction — average 4–6 months from order to occupancy for 8-storey buildings (12,000 m²).
• No hidden engineering fees: BIM-integrated structural design (Tekla + SAP2000) included — full load calculations, wind/snow/seismic reports, and as-built drawings provided free.
• Modular floor systems: Precast concrete slabs or composite steel-concrete decks; fire-rated up to 2 hours (tested per ASTM E119).
• Pre-certified components: All sandwich panels (rock wool/PUR/EPS), stair cores, and façade modules carry CE, CSA, or BV certification.

Multi-Storey Steel-Concrete Hybrid Structures Built for Long-Term ROI

We specialize in multi-storey steel-concrete hybrid structures — combining the speed of steel framing with the durability and acoustic performance of precast concrete. This approach delivers proven lifecycle economics: 30–50 year service life, 50-year structural warranty, and 30% lower total cost of ownership vs. traditional builds.

• Optimized load distribution: H-beam columns + moment-resisting frames handle vertical and lateral loads efficiently — reducing foundation costs by up to 22%.
• Crane-free assembly: Bolted connections and modular lift-and-place installation eliminate need for heavy cranes on tight urban sites.
• Thermal & acoustic performance: U-values as low as 0.22 W/m²K (with 120 mm rock wool core); STC ratings ≥55 dB for inter-unit walls.
• Future-ready adaptability: Mezzanine floors, rooftop PV integration, and HVAC-ready duct chases built into standard design packages.

Precast Concrete Components Manufactured to International Standards

All precast concrete components — wall panels, floor slabs, stair units, balconies — are produced in our CNAS-accredited plant using automated casting lines, digital mold calibration, and batch-traceable cement (P.O 42.5R). Every element meets EN 206, ASTM C33/C150, and local code requirements.

• Tight dimensional tolerance: ±1.5 mm flatness, ±2 mm alignment — critical for dry-joint assembly and façade continuity.
• Reinforcement precision: Fully welded rebar cages (ASTM A615 Grade 60), laser-scanned before pouring.
• Curing control: Steam-cured at 60°C for 8 hours → achieves >90% 28-day strength in 72 hours.
• Surface finish options: Exposed aggregate, acid-etched, or architectural formwork textures — no secondary cladding needed.

Apartment Building Systems Designed for Global Market Entry

Our apartment building systems are engineered for fast market entry — whether you’re launching a branded rental portfolio in Germany, scaling affordable housing in Kenya, or fulfilling Amazon’s warehouse-to-residential conversion pipeline in the US.

• Local code alignment: Pre-adapted design libraries for EU, GCC, ASEAN, ANZ, and North American jurisdictions — reduces permitting time by 40–70%.
• Buyer-label ready: OEM/ODM support includes custom branding on structural elements, BIM models, and technical documentation — minimum order: 100 m².
• Logistics-optimized packaging: Flat-packed wall/floor modules fit standard 40’ HC containers (up to 280 m² per container).
• Installation support included: Free detailed drawings + video guides; optional engineer dispatch (FOB/Tianjin or DDP available).

Manufacturer Direct — No Markup, No Middlemen, Full Traceability

We operate as a manufacturer-direct supplier, not a broker. With nine owned subsidiaries covering R&D, steel rolling, panel lamination, CNC machining, and logistics, we eliminate markup layers — passing verified cost savings to buyers.

• Transparent pricing: FOB Tianjin or CFR Dubai quotes include all factory costs — no surprise fees for drawing revisions, certifications, or sample processing.
• Raw material traceability: Mill test reports (MTRs), galvanizing thickness logs (≥85 µm Zn coating), and weld procedure specifications (WPS) provided with every shipment.
• Scalable MOQs: In-stock standard modules start at 100 m²; fully customized projects begin at 500 m² — with volume discounts applied at 2,000+ m².
• Payment flexibility: T/T (30% deposit, 70% before shipment), L/C at sight, or D/P — supported by Alibaba Trade Assurance and Sinosure export credit insurance.
