Explore our foundational pre-engineered structural fabrications, custom-designed to meet international industrial standards.
Offshore and onshore drilling locations represent some of the most unforgiving working environments on earth. Structural materials must withstand continuous exposure to high saline mist, violent wind loads (often reaching up to 250 km/h), constant seismic shifts, and extreme operational stresses. As energy exploration pushes into deeper waters and more remote geological formations, the requirements for top-tier structural steel have scaled exponentially.
At Hangzhou PYO Homes Co., Ltd., we understand that structural integrity is directly linked to operational safety and environmental protection. High-yield strength plates (such as API 2H, ASTM A572, and EN S355/S460 series) serve as the foundation of our oil rig facilities fabrication. By designing our structures to withstand corrosion classifications under ISO 12944 CX (Extreme Marine environments), we extend the operational lifespan of energy infrastructures while minimizing maintenance shutdowns.
Global procurement teams prioritize structural steel fabricators that can combine engineering compliance, material traceability, and large-scale manufacturing capacity. We align our operations with these exact priorities, providing the energy industry with structural modules that ensure zero-downtime operations in critical path infrastructures.
Providing standardized and customized modular steel systems for offshore drill platforms, onshore refineries, and supporting heavy industrial infrastructure.
Engineering sub-structures, jacket structures, and top-deck modules that are highly resistant to fatigue stress, heavy seas, and continuous hydrodynamic loading. Custom fabricated to offshore codes including AWS D1.1 and API RP 2A.
Standardized, pre-assembled structural steel pipe racks designed for chemical, gas, and oil transmission pipelines. Built to allow rapid field bolting, significantly reducing onsite welding time and hazardous site conditions.
Blast-proof and fire-resistant heavy metal wall panels and framing systems for control rooms, generator rooms, and hazardous material storage zones, strictly complying with safety protocols.
Heavy steel lattice masts designed for dynamic loading, hoisting weight capability, and torsional stability under intense drilling torque. Verified with finite element analysis (FEA) for safety margins.
Engineered multi-span metal buildings, warehouses, and storage depots designed to support high machinery loading, overhead cranes (up to 50 tons), and expansive clear-span storage requirements.
A Legacy of Precision Steel Fabrication and Industrial Architecture Solutions Since 2011
Founded in 2011 in Hangzhou, China, Hangzhou PYO Homes Co., Ltd. has evolved from a regional supplier of light steel framing components to an international leader in structural steel engineering and manufacturing. Our expertise spans heavy industrial facilities, pre-engineered buildings (PEBs), multi-span warehouses, and specialized offshore modules.
Our commitment to structural safety is backed by a advanced production infrastructure. We operate precision CNC cutting lines, automated submerged arc welding systems, and advanced non-destructive testing (NDT) modules. This integration ensures that every structural element, from massive column weldments to secondary structural purlins, is manufactured to within tight tolerance specifications.
With an export network reaching Asia, the Middle East, Africa, and South America, PYO Homes delivers comprehensive services including custom detailing, shop drawing preparation via Tekla Structures, structural calculation reports, complete logistics support, and onsite installation guidance.
A systematic approach to solving cost overruns, quality variations, and lead-time delays in international steel projects.
Procuring raw steel without clear Mill Test Certificates (MTC) exposes projects to catastrophic material failures. PYO Homes offers complete heat-number traceability, matching every structural plate to its source metallurgical test report, guaranteeing ASTM, GB, or EN compliance.
Onsite fitment errors can delay projects for months. Our QA program includes a pre-assembly phase inside our factory. We test-fit structural components, verifying layout clearances, bolting hole configurations, and connection tolerances before shipping container packing.
Offshore oil rig structures demand heavy corrosion barriers. We provide professional surface preparation up to Sa 2.5 standard, followed by high-thickness hot-dip galvanization or multi-layer epoxy coating systems formulated to last 25+ years in harsh marine conditions.
Shipping large-scale structural sections is complex. Our packaging team uses steel frame bundling, protective shipping crates, and sequential loading plans. This ensures components arrive undamaged and are unloaded in the exact sequence needed for erection.
We design to meet specific national building standards. Whether your project requires AISC specifications in South America, BS standards in Africa, or Eurocodes in European offshore zones, our structural engineers adapt structural details to ensure local building permits are approved.

The steel construction sector is moving rapidly towards digital integration and carbon footprint reduction. PYO Homes is at the forefront of this shift by implementing full BIM (Building Information Modeling) workflows from conceptual design to shop drawing development. This allows real-time clash detection, saving structural erection time and materials onsite. Additionally, we are actively integrating green steel fabrication methodologies, including energy-efficient electric arc furnace (EAF) steel sourcing and VOC-free, low-emission heavy industrial coatings, to align with global environmental policies.
Our quality department monitors every fabrication step. Material entry checks, dimensional tolerance validation, ultrasonic inspection of full-penetration butt welds, and dry film thickness (DFT) paint testing are performed on every batch. Each structural module is stamped with a tracker tag, allowing for tracing back to original manufacturing files and testing records.
This systematic approach minimizes onsite errors. We work closely with third-party testing agencies (including SGS, BV, and Lloyd's Register) to provide global project teams with certified documentation validating that all shipped fabrications meet international engineering expectations.

We typically use high-strength structural steel plates such as API 2H Grade 50, ASTM A572 Grade 50/60, and EN 10025 S355G8+M or S460 series. These grades provide the necessary yield strength, low-temperature toughness, and fatigue resistance required to withstand dynamic wave loading and structural stresses in sub-zero marine environments.
We follow ISO 12944 standard guidelines for protective paint systems. For C5-M (Marine) and CX (Extreme Marine) atmospheres, we perform grit blasting to Sa 2.5 white-metal finish, followed by hot-dip galvanization (min 85-100 microns thickness) or a multi-coat paint system (zinc-rich epoxy primer, epoxy micaceous iron oxide intermediate coat, and polyurethane topcoat) totaling over 320 microns dry film thickness.
Yes. Our engineering division prepares detailed 3D models and structural calculations in Tekla Structures and STAAD.Pro to verify compliance with AISC 360 (for US projects), Eurocode 3 (EN 1993, for European and international sites), or regional building codes including GB (Chinese Standards) and AS/NZS standards.
All structural members are systematically labeled to match the assembly drawings. For major projects, we provide complete technical manuals, 3D erection animations, and virtual support. Upon request, we can also dispatch structural engineering supervisors and master builders to your project location to direct local labor teams during installation.
