Explore our leading range of high-strength industrial structures custom-engineered for modern manufacturing, logistics, and agricultural systems.
Dongguan Metro Build Co., Ltd. is a leading China prefabricated warehouse building manufacturer specializing in the design, production, and supply of high-performance steel warehouse solutions for customers worldwide. With extensive experience in the steel structure industry, the company is committed to delivering durable, cost-effective, and customized building systems that meet the evolving needs of industrial and commercial sectors.
By leveraging state-of-the-art computational structural design (utilizing TEKLA, SAP2000, and PKPM software suites), we optimize high-strength steel frames (Q235B and Q355B grades) to survive extreme environmental stresses, from high-wind hurricanes in coastal regions to seismic loads in tectonic belts. Our solutions provide maximum column-free clear spans, accelerating structural assembly processes and minimizing foundation load requirements.
Information Gain Focus: Unlike standard steel builders, Metro Build utilizes a proprietary fabrication workflow that integrates anti-corrosion painting and pre-punched structural bolt holes in an indoor automated environment, ensuring error-free global deployment.
100% traceabilty of hot-rolled section steel and structural steel plates.
AISC & Eurocode-compliant bespoke engineering configurations.
Decoding macro trends: how smart warehousing, cold-chain operations, and modular structures drive capital efficiency.
Modern industrial supply chains demand precise heights and flat floor tolerance standard (Class FM1/FM2). Our steel designs support high bay racks, mezzanine platforms, and floor structures that mitigate structural deflection for automated guided vehicles (AGVs) and cranes.
With prefabricated insulated PIR/polyurethane panels, our cold storage designs minimize thermal bridging. Designed explicitly for fruit, vegetable, meat, and pharmaceutical storage, these warehouses maintain stable internal temperatures while reducing operational electricity draw by up to 30%.
From livestock facilities with specific environmental ventilation, moisture mitigation, and waste management setups to crop storage warehouses with low-cost commercial structures, we maximize usability with multi-span portals designed for the modern agribusiness footprint.

| Wall & Roof Cladding Systems | PIR (Polyisocyanurate) / Rockwool Sandwich Panels | Color-coated steel skin (PVDF or SMP coating) | High thermal resistance (R-value up to 35), soundproofing, Class A1/B1 fire retardancy. |
| Fasteners & Anchor Bolts | High-strength structural bolt assemblies (Grade 8.8/10.9) | Electro-galvanized or Dacromet coated | High shear resistance, secure structural joints, dynamic load capacity under wind drift. |
For high-moisture agricultural systems or near-sea coastal warehouses, the primary threat is material degradation. Metro Build offers advanced corrosion protection: utilizing hot-dip galvanization matching ISO 1461 standards, which provides up to 50 years of maintenance-free service. For thermal containment, our polyurethane (PU) insulation systems feature double-tongue-and-groove joints that prevent cold air drafts and atmospheric ingress, rendering our structures optimal for high-performance cold chain applications.
By shifting structural steel fabrication from the construction site to our state-of-the-art factory in Dongguan, China, we ensure high quality. Components are pre-welded, pre-cut, and pre-punched according to digital CNC layouts. This decreases construction downtime, reduces labor overhead by over 40%, and prevents typical environmental complications associated with open-air construction.
Adapting steel structure design to diverse climates, regulatory terrains, and industrial applications.
In highly seismically active zones, steel frames utilize moment-resisting connections and cross-braced configurations. The relative elasticity and high weight-to-strength ratio of Q355B steel allow structures to deform and absorb energy without brittle failures, safeguarding storage assets.
For Northern Europe and North America, roofs are engineered with optimal pitch angles (10% to 15%) and thick cold-formed purlins designed to carry heavy live snow loads (up to 2.5 kN/m²). Cladding uses rockwool core sandwich panels for advanced thermal protection.
Highly saline maritime air and ammonia-heavy agricultural atmospheres rapidly degrade basic iron structures. We offer premium hot-dip galvanized coatings and PVDF cladding paint systems that stand up to C4 and C5 high-corrosive zone specifications.
The strategic location of Dongguan Metro Build Co., Ltd. inside China's Pearl River Delta manufacturing hub guarantees unique structural engineering and logistical advantages. This industrial ecosystem yields fast turnaround times, direct access to premium iron and steel mills, and optimized export logistics.
Metro Build offers end-to-end global project management, handling project consultation, structural design, manufacturing, quality inspection, packaging, and international shipping coordination. We simplify your supply chain by delivering ready-to-assemble steel warehouses directly to your project site.
How Metro Build is embracing carbon neutrality, smart building information modeling (BIM), and high-durability green steel.
By simulating structural clashes and assembly sequencing in a virtual environment before cutting raw metal, we eliminate on-site project delays and design discrepancies.
Steel is 100% recyclable. We are optimizing our production lines to utilize steel alloy options that support structural energy efficiency goals and green building initiatives like LEED certification.
We are engineering columns and beams to accommodate structural health monitoring sensors that track real-time deflection, load stresses, and corrosion progress over decades of usage.

We design in accordance with global engineering frameworks, including the American Institute of Steel Construction (AISC) standards (such as ANSI/AISC 360-16 specification for structural steel buildings), the Eurocodes (EN 1993 for design of steel structures), and China's national standard GB 50017-2017. Our software allows us to calculate specific local load combinations, including snow loads, seismic factors, and wind velocities up to 250 km/h.
PIR (Polyisocyanurate) sandwich panels provide higher thermal efficiency (R-value of ~7.2 per inch of thickness) than Rockwool (R-value of ~3.8 per inch), making PIR ideal for temperature-controlled cold storages. However, Rockwool panels offer superior fire-resistance ratings (up to Class A1, non-combustible), making them suitable for hazardous material plants, crop processing workshops, and poultry structures.
For highly corrosive C4 or C5 environments, we offer hot-dip galvanization (ISO 1461) where steel elements are coated in molten zinc (minimum coating density of 85 microns / 610 g/m²). Alternatively, we apply a high-performance industrial paint system consisting of a zinc-rich epoxy primer (80 microns), an epoxy micaceous iron oxide intermediate coat (100 microns), and an acrylic polyurethane topcoat (50 microns).
