Metal Building Manufacturers for Industrial Envelope Systems
Beijing Duowei Eispt International Project Technology Co., Ltd. works on industrial building envelope systems: metal envelope and supporting steel structure, floor deck, cleanroom enclosure and building-integrated photovoltaics, offered as coordinated systems with design, manufacture and installation.

Five systems, one coordinated approach
The company profile states that the company was founded in 1983 and has focused on the green industrial building envelope sector for more than 40 years. Its main business covers the production and sale of metal envelope systems with supporting steel structure, floor deck systems and cleanroom enclosure systems, together with system solutions that combine design and research, intelligent manufacture and installation services.
That breadth matters for buyers, because an industrial building is rarely a single purchase. The envelope, the frame, the floors and any photovoltaic surface meet at shared junctions, and a supplier that plans them together can keep those junctions in one conversation. This site is organised the same way: by system, by sector, and by the inquiry steps that connect them.
What this site does and does not publish
This site describes systems and inquiry steps. It does not publish specification tables, order figures or lead-time figures. Where a figure comes from the company profile, it is labelled as such, and where a requirement matters to your project, the page asks you to confirm it in your inquiry rather than presenting it as a published fact.
Certificates are handled the same way. Apart from the single product news item noted on the envelope pages, this site states only that certificates are available upon request. No certificate number or issuing body is stated anywhere on this site.
Metal Building Envelope
The envelope system as a whole: walls, roofs and their junctions, planned together with the supporting steel structure.
Steel Building System
The frame that carries the building, coordinated with the envelope it supports.
Composite Floor Deck
Floor deck systems planned together with the frame below and the floor build-up above.
Cleanroom Enclosure System
Industrial cleanroom enclosures for controlled interiors, described at system level.
Building Integrated Photovoltaics
Photovoltaic equipment that forms part of the roof or wall, planned as one system with the building surface.
