Explore our core portfolio of pre-engineered, high-durability steel structural assemblies and plants, fully customized for global energy infrastructure, thermal power, and industrial processing operations.
In the highly demanding and hazardous sectors of Oil, Gas, Petrochemical, and Industrial Power generation, structural integrity is paramount. Critical infrastructure requires structural components designed to withstand explosive blast loads, seismic activities, cyclic fatigue, and highly corrosive marine or onshore chemical environments. As a premier Custom OEM Steel Structure Oil and Gas Facilities Supplier & Exporter, Hangzhou PYO Homes Co., Ltd. delivers engineered-to-order structural solutions that satisfy these complex requirements.
Founded in 2011 in Hangzhou, China, our company initially established its footprint as a regional manufacturer of light steel framing. Recognizing the international shift towards modular, fast-track, and highly standardized industrial construction, we systematically expanded our engineering capabilities. By 2016, we had scaled to offer full-cycle design, detailed drafting, precision fabrication, testing, and comprehensive global delivery of pre-engineered, heavy-duty industrial structural complexes.
We provide specialized OEM steel fabrication solutions across all domains of the energy sector, offering reliable frameworks designed to prevent catastrophic structural failure and minimize plant downtime.
Engineered to support heavy multi-tier process piping configurations, our modular pre-assembled steel pipe racks absorb dynamic hydrodynamic loads, temperature-induced expansion/contraction, and seismic stresses.
Supporting equipment integration (pumps, compressors, manifolds, valves) on high-rigidity structural steel bases. Skids are structural skeletons manufactured to tight geometric tolerances for effortless plug-and-play field installation.
From catalytic cracking unit housings and fractionator tower support structures to complex platforms, catwalks, staircases, and handrails engineered in compliance with OSHA, BS, and AS/NZS codes.
Manufacturing critical components for high-risk oil and gas systems requires robust process control. At our Hangzhou fabrication facility, we implement modern manufacturing technologies to achieve unparalleled structural precision, reliable lead times, and cost optimization.
Our production line features automated heavy CNC beam drills, multi-torch gantry plasma cutting, and CNC plate processors. These tools enable digital CAD-to-CAM transitions, translating complex structural designs directly to machining instructions. This automation minimizes hand-detailing and welding errors while ensuring hole alignments meet AISC/AISC-360 structural requirements.
Welding is the cornerstone of structural integrity for petrochemical infrastructure. We employ certified ASME Section IX and AWS D1.1 welders to execute Submerged Arc Welding (SAW), Gas Metal Arc Welding (GMAW), and Shielded Metal Arc Welding (SMAW). Prior to paint application or galvanization, we conduct comprehensive testing: Visual Testing (VT), Ultrasonic Testing (UT), Magnetic Particle Testing (MT), and Radiographic Testing (RT) to guarantee zero welding defects.
To survive aggressive environments such as offshore spray and sulfur-rich refinery atmospheres, our steel structures undergo grit-blasting to standard Sa 2.5/SSPC-SP10. We offer multi-coat epoxy primer systems, polyurethane topcoats, and premium hot-dip galvanization according to ISO 1461/ASTM A123 to provide durable barrier protection.
"Through structural engineering modeling, we optimize our raw steel yield and structural profiles. This process offers global EPCs up to 25% savings in transport and steel weight without sacrificing structural load capacities."
The global oil, gas, and renewable chemical industries are shifting towards lower carbon footprints and smarter structures. PYO Homes stands at the forefront of this industrial transition by embedding sustainable practices and smart design processes directly into our OEM structural steel fabrication.
We are actively expanding our raw material sourcing network to include low-carbon electric arc furnace (EAF) steel and hydrogen-reduced steel products. By optimizing structural designs, we reduce total material volume and lower the embodied carbon footprint of large industrial facilities.
Integrating mechanical stress sensors, fiber-optic strain gauges, and corrosion monitoring systems directly into critical structural joints. This transformation allows real-time structural health monitoring (SHM), providing operators with analytical data to schedule preventive maintenance before failures occur.
As global energy companies convert existing refineries to handle green hydrogen, we are designing structural foundations and platforms customized for highly volatile hydrogen storage, high-pressure compression units, and cryogenic piping lines.
Operating globally means complying with localized building regulations, environmental laws, and rigorous engineering design codes. Below is our compliance matrix demonstrating the alignment of our fabrication facilities with international engineering authorities.

We implement complete raw material heat traceability. Every batch of steel plates, H-beams, and structural tubing sourced from tier-one steel mills is accompanied by Mill Test Certificates (MTC) conforming to EN 10204 3.1 or 3.2. From raw material receipt, cutting, fit-up, and welding to surface preparation and shipping, we assign a unique tracking code to each member. This code links to the digital production record containing welding records (WPS/PQR) and NDT inspection reports.
Yes. Our engineering center works extensively in Tekla Structures, AutoCAD, and PKPM, allowing us to import 3D models directly from PDMS, SmartPlant 3D, and Revit. This direct model integration prevents component clashes, guarantees structural alignment for process equipment and pipe openings, and facilitates pre-assembly checks before export shipment.
Petrochemical structural steel structures are bulky and prone to damage during sea shipping. We pack steel members inside heavy-duty customized steel frames (skids) or bundle them using specialized timber spacers and steel bands. Flat faces and machined flanges are coated with rust preventive oil and wrapped with protective membranes. Critical bolt connections are packed in waterproof wooden crates. This packaging strategy allows rapid container loading and unloading while preventing mechanical damage and corrosion.
Yes. We source steel grades designed for low-temperature applications, such as ASTM A572 Grade 50 Charpy V-Notch (CVN) tested steel, or EN 10025 S355ML/NL grades, which maintain impact toughness at temperatures down to -40°C or -50°C. For seismic zones, we follow AISC 341 Seismic Provisions for Structural Steel Buildings, utilizing specialized moment-frame connections, high-strength tension bolts, and precise welding methodologies to ensure structures deliver ductile performance during seismic events.
