Custom Outdoor
Structures Manufacturer.
Your Design.
Our Supply Chain.
As a wholesale custom outdoor structures manufacturer, we engineer your pergola, gazebo, pavilion, or shed to local wind and snow code — in aluminum, steel, or wood — source it from audited factories, inspect every weld and powder coat to AQL 2.5, then ship it with a full compliance dossier. Same materials as domestic. 30–50% less. One partner, end to end.
Pergolas. Gazebos. Pavilions. Sheds.
Carports. Greenhouses.
One Engineering Team. One Factory.

Aluminum vs Steel vs Wood.
The Engineering Decision That Defines Your Product Line.
Material selection is not an aesthetic choice — it determines structural performance, corrosion resistance, maintenance requirements, shipping cost, and warranty liability. Here is the engineering data, side by side.
Engineering Specs by Material.
What Your Retail Buyer's Technical Sheet Needs.
When your retail partner asks for span ratings, load capacities, and fastener grades — these are the numbers that go on the spec sheet. Every value below is production-validated and documented in your compliance dossier.
Four Problems Every Structures Buyer Faces.
And How We Solved Each at the Factory Level.
Your manufacturing cost is 40% above where it needs to be.
Three materials. Three suppliers. Three sets of problems.
"Custom" usually means picking from a catalog of 12×10 and 10×10.
Lead times stretch. Communication stops. The factory you visited isn't the one running your order.
Four Capabilities Most
Structure Factories Don't Have.
Most outdoor structure suppliers are trading companies with a catalog and no factory access. These four capabilities — all managed directly by OGPS — are what separate a supply chain partner from a middleman.
Multi-Material, One Partner
Aluminum extrusion specialists. Steel fabrication and roll-forming partners. Wood milling and joinery workshops. All vetted, audited, and managed under our QC system in Guangdong. One PM coordinates every production stream. Your entire outdoor structures category — pergola, gazebo, pavilion, shed, carport, greenhouse — ships as one consolidated container under one bill of lading.
Engineered to Your Climate Zone
Wind-load calculations per ASCE 7. Snow-load per local building code. Seismic considerations where required. We engineer the post section, beam depth, truss geometry, and fastener specification to YOUR destination market — not a generic "one size fits all" design. Full calculation package included in your compliance dossier.
Custom Tooling. Protected IP.
Custom aluminum extrusion dies. Proprietary steel connector stamping tools. Branded post cap molds. All sourced through our partner tooling network — no 8–12 week external mold vendor delays because we manage the pipeline across multiple shops. Your tooling is NNN-protected and stored in access-controlled inventory. When you own the tooling, nobody else can run your design.
Flat-Pack Engineering Built In
KD design isn't an afterthought — it's engineered into the structure from the first CAD revision. Nestable louver panels. Detachable post-to-beam connectors. Stackable truss modules. ISTA 3A drop-tested packaging. 40–60% cube reduction vs assembled structures. Dense container loading = lower freight per unit = better landed cost.
Which Structure for Which Market?
An Engineer's Recommendation Matrix.
Your retail buyer doesn't need a catalog of 200 SKUs. They need the right structure for their customer's use case. Below is our application matrix — built from 15 years of engineering structures for North American and European markets.
Everything You Need to Know
Before Starting a Structures Program.
Pergolas and gazebos: 50–100 units per SKU. Pavilions: 25 units. Sheds and cabins: 100 units. For fully custom OEM designs with dedicated tooling, MOQs are 200–300 units. Phased ramp-ups available for new brands. Annual procurement volumes of $400K+.
Existing platform SKUs: 45–60 days. New OEM/ODM designs: 90–120 days including engineering review, sampling, tooling, and packaging validation. Ocean transit: 25–35 days to NA/EU ports. We backward-schedule from your retail set date.
Yes — standard on every project. We calculate post sections, beam depths, and truss geometry against ASCE 7 (wind) and your local snow load code. For extreme climates, we engineer larger post sections, additional truss members, and higher-grade fasteners.
Yes. Density-optimized FCL consolidation combines heavy items as ballast with bulky KD structures in one 40HQ. One purchase order, one shipment, one point of contact. Typical 15–25% freight savings versus fragmented LCL shipping.
Aluminum frames: 5-year structural + finish integrity. Steel structures: 2-year rust-perforation. Wood structures: 2-year structural defect + warping. Extended terms available for enterprise accounts. Claims processed within 72 hours. Spare-parts inventory maintained in Rotterdam for EU customers.
Yes. Every SKU ships with an illustrated multi-language assembly manual, hardware kit, and retail-ready packaging if required (branded cartons, UPC barcodes, pallet displays). Every sampled unit is assembly-tested during pre-shipment inspection.
ISO 9001:2015 QMS, BSCI social compliance, CE marking (EU). Structural calculations per ICC/IBC. Fastener pull-test and cross-hatch adhesion (ISO 2409). Salt-spray corrosion (ASTM B117, 500+ hr). ISTA 3A packaging integrity. CARB Phase 2 / EPA TSCA Title VI for wood components.
