Request Steel Pipe QuoteTransforming Global Housing via Industrialized Steel Prefabrication
The paradigm of modern residential and commercial real estate development has decisively shifted from cast-in-place masonry toward precision-engineered off-site steel framing. Operating from twin industrial epicenters spanning 1,500 acres across Tianjin and Tangshan, China, Tianjin Huizhong Xinyu (HZXY) harnesses a cumulative annual raw-steel throughput exceeding 10 million metric tons.
Unlike conventional intermediaries who mark up sub-assemblies, our fully vertically integrated supply chain enables real estate developers, EPC contractors, and public works authorities to acquire direct-from-factory steel frame manufactured homes at true wholesale discount pricing. By combining structural H-beams, cold-formed framing profiles, hot-dip galvanizing, MEP drainage and conduit solutions, and modular assembly engineering within a single production umbrella, project timelines are reduced by up to 58% while eliminating procurement friction.

Essential clarifications regarding pricing mechanics, minimum order thresholds, customization limits, code compliance, and logistics guarantees.
How does HZXY deliver discount factory pricing on steel frame manufactured homes compared to local distributors?
HZXY operates direct manufacturing and processing mills inside the Daqiuzhuang, Tianjin and Tangshan steel clusters across 1,500 acres. By utilizing our own 10-million-ton annual raw material rolling capacity, cutting, CNC profiling, and galvanizing lines, we eliminate intermediary markups, third-party logistics margins, and multiple handling fees. You purchase at direct blast-furnace tier-1 wholesale rates.
What specific international building codes and seismic/wind load criteria are accommodated?
Our structural engineering team designs framing systems according to the US International Building Code (IBC 2024 / AISI S100), Eurocodes (EN 1993 for steel structures), and Australian/New Zealand Standards (AS/NZS 4600). We regularly engineer solutions certified for seismic Zone 4 categories and cyclonic wind conditions exceeding 240 km/h (150 mph).
Can developers consolidate diverse structural, piping, and valve items into a single container shipment?
Yes. One of our core competitive advantages is consolidated Bill-of-Materials (BOM) logistics. You can combine primary H-beam portal columns, light-gauge steel wall framing, PVC electrical conduit, water supply pipes, and municipal-grade butterfly/gate valves into unified 40HQ container shipments, significantly minimizing ocean freight dead space and customs clearance expenses.
What are your standard Minimum Order Quantities (MOQ) and production lead times?
For standardized modular housing frames or flat-pack container units, our MOQ starts at 2 complete units or 20 metric tons of raw structural framing profiles. Standard manufacturing lead time at Tianjin Port averages 10 to 18 calendar days following final CAD/CAM shop-drawing freeze and LC/TT deposit confirmation.
What quality documentation, inspection protocols, and mill test certificates accompany shipments?
Every dispatch is accompanied by official Mill Test Reports (MTR) according to EN 10204 3.1 certifying heat numbers, chemical composition, and tensile/yield properties. Buyers may also appoint independent inspection agencies (SGS, Bureau Veritas, TÜV, Intertek) to conduct ultrasonic testing, dimensional verification, and coating thickness audits prior to container sealing.
What anti-corrosion protection is specified for harsh tropical or coastal environments?
We offer multiple anti-corrosion grades ranging from hot-dip galvanizing (HDG) with zinc coatings from 275 g/m² up to 600 g/m² (85µm thickness), aluminum-zinc-magnesium (ZM310) with self-healing sheared edges, up to heavy epoxy and fluorocarbon spray finishes exceeding ISO 12944 C5-M marine atmospheric protection standards.
