From a 2015 US Order to 20+ Countries: Tengshuo Marks 15 Years of Container House Manufacturing

Guangzhou, China — November 2026 — Tengshuo Integrated Housing Co., Ltd. has reached 15 years of container house manufacturing. Founded in 2011, the company shipped its first export order to the United States in 2015 and now supplies prefabricated, expandable and foldable container houses and mobile prefab bathrooms to more than 20 countries across North America, Europe and South America.

Production capacity stands at around 1,500 units per year, with an annual output value of RMB 50 million. Standard units typically leave the factory 15 to 25 working days after drawing approval.

It Started With One Container House to the United States

The company's first export shipment left for the United States in 2015 — a single container house for a site contractor. It was a small order by any measure, but it set the pattern for everything that followed: drawings approved before production, the unit packed as a complete building rather than a pile of panels, and documentation that let a crew on the other side of the Pacific assemble it without a single phone call to China.

"The first container we sent to the States was one unit, and we spent longer on the drawings and packing list than on the steel," said Mr. Bruce, General Manager of Tengshuo Integrated Housing Co., Ltd. "That order taught us what export actually means. The building has to arrive complete, documented, and buildable by people who will never meet us. Eleven years later, that is still the standard every order is measured against."

That first US order opened the door to North America, and the same approach carried the company into Europe and South America. In the decade since, the product range has expanded from a single container house design into four distinct lines.

Four Product Lines Built on One Modular Platform

The range is organised around a single modular platform, which means a buyer can specify one unit or a complete multi-block complex from the same supplier.

Prefabricated container houses are built on standard container footprints and arrive as finished units or flat-packed kits, ready to be lifted into position and connected to site services. They are the default choice for site offices, storage, security posts and single-unit accommodation.

Expandable container houses ship in a compact transport configuration and unfold on site to create a working floor area several times the shipping volume. They are usually specified where floor space matters more than freight cost — site canteens, clinic rooms, small offices and family accommodation.

Foldable container houses fold flat for transport, cutting shipping volume per unit and reducing cost on long-haul routes. Once on site, the panels fold out and lock into place, and the unit is ready for fit-out.

Mobile prefab bathrooms are standalone toilet and shower units supplied as complete wet rooms, used for construction site camps, events, farms and public facilities where permanent plumbing is not available.

Each line can be delivered as a bare shell or fully fitted out — insulation, wall and floor finishes, electrical distribution, plumbing, air conditioning, doors and windows — depending on how much site work the buyer wants to take on.

1,500 Units a Year, and a 15–25 Day Lead Time

Capacity currently runs at approximately 1,500 container house units per year across the four lines. For buyers, the more useful number is lead time: standard configurations typically ship 15 to 25 working days after drawing approval, with custom layouts and full fit-out running longer depending on specification.

Every order goes through a pre-shipment inspection before loading, and buyers are welcome to appoint their own QC team or a third-party agency to inspect at the factory prior to shipment.

CE Marked Under EN 1090-1, Certificate 2787-CPR-01609

Container house structural components are certified for factory production control under the EU Construction Products Regulation (No 305/2011).

• Certificate — 2787-CPR-01609, Certificate of Conformity of the Factory Production Control
• Notified Body — OTC Bulgaria Ltd. (Organization for Technical Conformity), Notified Body No. 2787
• Standard — EN 1090-1:2009+A1:2011, with execution to EN 1090-2, execution class EXC2
• Assessment system — System 2+, covering notified body surveillance of factory production control and the manufacturer's own initial type testing
• Manufacturing processes in scope — cutting, drilling, welding, assembly, non-destructive testing (NDT) and corrosion protection
• Validity — first issued 6 January 2026, valid to 5 January 2029

For buyers, EXC2 is the operative detail. EN 1090-2 divides steel structures into execution classes by consequence of failure, and EXC2 is the class that covers load-bearing building structures — the class most container house and modular building projects are specified to. Certification to EXC2 means welding procedures, welder qualification, NDT and corrosion protection are all controlled and audited, rather than self-declared.

Every EU-bound shipment of structural components is accompanied by a Declaration of Performance drawn up under Annex ZA of EN 1090-1, together with the CE marking and the certificate number, so the documents can be checked against the Notified Body's register.

Independently Verified: SGS, Bureau Veritas and ICR

Alongside the CE certification, the company's production is independently audited, inspected and verified by three further bodies.

• SGS — independent factory audit and pre-shipment product inspection. Inspection reports are issued per order and can be verified with SGS against the report number.
• Bureau Veritas (BV) — third-party certification and audit of the company's production process and management system.
• ICR Co., Ltd. — Verification of Conformity No. ICR/VC/HCC250903, assessed against EN 1090-1:2009+A1:2011 under CPR (EU) 2011/305. Issued 2 September 2025, valid to 1 September 2030. The scope covers expandable, folding, detachable and flat-pack container houses, standard container houses, capsule houses, Apple cabin houses and dome houses.
• Invention patents — multiple patents covering the container house structure and folding mechanisms.
• Verifiable documentation — certificate and report numbers are quoted on quotations and inspection documents, so a buyer can confirm them directly with the issuing body instead of relying on a PDF from a supplier.

Because the units are shipped as finished buildings, the paperwork travels with the steel. Buyers receive the Declaration of Performance, inspection report, packing list, material test reports, assembly drawings and foundation requirements as one document set, and can cross-check any of it with OTC, SGS, BV or ICR before the container is loaded.

Exporting Since 2015: Three Continents, Three Sets of Requirements

Export work now spans three regions, each with its own engineering priorities.

In North America, the emphasis is on electrical systems matched to local code requirements, wind and snow loading by state, and straightforward site assembly for contractors working with limited labour.

In Europe, projects are specified for cold-climate insulation values, snow and wind loading, and the structural documentation European buyers need for local permitting.

In South America, the priorities are corrosion protection in coastal and humid environments, seismic and wind resistance, and simplified assembly where skilled labour is limited.

Built for Hotels, Camps and Industrial Facilities

The same modular platform serves very different building types:

• Hospitality — hotel annexes, resort villas, guest rooms and reception buildings
• Commercial — site offices, sales centres, staff canteens and dormitories
• Industrial — workshops, warehouses, tool stores and worker accommodation
• Construction — site camps, washrooms, security cabins and temporary facilities

Customisation covers dimensions, layout, facade treatment, interior specification and branding, so a project can be delivered as a recognisable building rather than a standard box.

Visit the Factory

Buyers comparing suppliers usually want to see the steel before they sign, so both of our production sites are open to customers, their own QC teams and third-party inspectors.

Náš Guangzhou facility sits close to the Nansha and Yantian container ports, which keeps export handling, consolidation and loading on a short chain to the ship.

A visit typically covers material and insulation samples, a finished unit on display, and a walk-through of the production line. Visits can be arranged through the contact page, and the team will coordinate timing with production schedules and inspection appointments.
