What Roxtec China does

Roxtec China (legal name: 瑞克赛克密封系统（上海）有限公司 / Roxtec Sealing System (Shanghai) Co., Ltd.) is the China regional subsidiary of Sweden-based Roxtec International AB, a privately held global manufacturer of modular cable and pipe sealing systems headquartered in Karlskrona. The company was founded in 1990 by Mikael Blomqvist, with the Chinese entity established in 1997 and headquartered in Shanghai at 17/F, Future Asset Building, 166 Lujiazui Ring Road, Pudong. Roxtec China serves infrastructure, marine, offshore oil and gas, power (including renewables), manufacturing, and process industries, providing certified sealing solutions that protect against fire, water/gas ingress, electromagnetic interference (EMI/EMP), and explosion hazards.

The core of the product offering is the proprietary Multidiameter™ (多径) technology — modular sealing systems with peelable rubber core layers that adapt to different cable and pipe sizes within a single frame. The portfolio spans rectangular and round frames (S, SF, G, GH, R, RS series), specialized variants for EMC shielding (ES series), explosion protection (Ex/ATEX), grounding (BG™), fire-rated plastic pipe penetration (Sleev-it™), and high cable density applications (HD, CSP, FlamePlus™). In 2025 Roxtec launched the HD 72 transit system, Mobility Seals for rolling stock, and the CSP cable transit system, extending the addressable market into rail and electrical cabinet applications.

Roxtec's business model combines hardware sales of certified sealing components with a complementary software suite: Roxtec Transit Designer™ (free web-based design tool with 70,000+ users), Transit Build™ (installation quality control), and Transit Operate™ (asset lifecycle management). Approximately 250 custom solutions are engineered per month. Go-to-market is direct enterprise field sales with engineering support, supplemented by global subsidiary network (30 subsidiaries across 80+ markets) and BIM/CAD integrations with platforms including Autodesk Revit, Tekla, MagiCAD, ePlan, and FORAN. Roxtec Group reported FY2025 sales of 4,072 MSEK with 1,120 average employees globally. The group is owned by Swedish holding company Mellby Gård Holding AB; current leadership comprises CEO Magnus Holmberg and Board Chairman Hans Stråberg.
