SIB Schlemmer

What SIB Schlemmer does

SIB Schlemmer (legal name SIB – Solutions Industry & Building) is a French privately held industrial manufacturer, structured as a Société par Actions Simplifiée (S.A.S.) with €9,500,000 in share capital, headquartered in Boulay-Moselle, France. Founded in 1922 and operating with 101–250 employees, the company designs, manufactures, and distributes cable glands, cable gland accessories, cable penetration seals, and cable carrier chains for industrial, hazardous-area (ATEX), railway, and building applications. Its product portfolio is organized into three verticals — Industry, Building, and Railway — each with a dedicated catalogue, and features proprietary sub-brands such as WADI-TEC and SIB-TEC, including the recent SIB-TEC LF lead-free line.

The company's core technology centres on mechanical cable-entry and sealing solutions engineered for demanding environments, including explosion-proof (Ex d/e) glands certified to ATEX/IECEx for Zones 1, 2, 21, 22, ingress protection ratings up to IP68 and IP69K, temperature ranges from -60°C to +200°C, and compliance with EN 45545 for railway fire safety. SIB holds an unusually dense certification stack — ATEX, IECEx, INMETRO, UL, VDE, DNV GL, EAC, ENEC, UKCA, PCEC, NEMA 4X, RoHS, and REACH — providing regulatory access to European, North American, Brazilian, Chinese, and Eurasian markets.

Commercially, SIB generates revenue through hardware sales of cable glands and accessories via a quote-based B2B pricing model. Distribution combines a direct France sales network covering all departments, a French distributor network extended to overseas territories (DOM-TOM), and global export partners, supplemented by event-driven demand generation at European and North African trade shows (SIDEC Lyon, SEPEM Colmar, SPS Italia, NAPEC Algeria, Egypt Electrics, Amper Czech Republic, Gen.Ead). Customer segments are industrial/manufacturing, building/construction, and railway/transportation, with no named end-customer accounts disclosed.
