The company Tremis s.r.o. produces components for installation of lighting protection system and grounding which meet the requirements of lightning protection according to standards ČSN EN 62305. Each single component in lighting and grounding system is solved as per its use and according standards for components lightning protection ČSN EN 62561.
The company Tremis s.r.o. provides for its own products certiﬁ cation according to European standards in Electrotechnical testing institute in Prague. On the base of testing protocols are issued certiﬁ cates for each category of products. The category of clamps also has testing datasheet with complete information about each product.
The company Tremis s.r.o. recommends to investors to solve design of grounding and lighting system with authorized designer, who has enough experiences and has technical support from us as producer. For realization, we recommend specialized and qualiﬁ ed companies. Outcome would be not only functional lightning protection but architecturally clean design too.
The company Tremis s.r.o. has established Quality Management System according to ČSN EN ISO 9001:2016. Certiﬁcate has been issued by TÜV SÜD Czech s.r.o. for range of activity: development, production and selling of components for lightning protection and grounding.
The company Tremis s.r.o. offers range of product in galvanized, stainless steel, copper and aluminium alloy.
Components for lightning protection and grounding in hot dip galvanized steel
Used material are: steel S235 or DD11, malleable cast iron and plastic with UV stabilization.
For ballast anchor is used gravel or concrete blocks resistant to temperature changes.
Surface ﬁ nish of Steel products are made by hot dip galvanizing, where zinc layer guarantee long-life and anti-electrochemical protection. The thickness zinc layer is according to the technical conditions of standards ČSN EN ISO 1461.
Fasteners M8 and M10 are hot dip galvanized and meet quality according to the standard ČSN EN ISO10684. For economic variant is used electro-galvanized fasteners M6.
Components for lightning protection and grounding in cooper – Cu
The material used for the production of clamps is copper of standard E-Cu 57 (Cu- ETP/CW004A), other products are made from copper without a requirement for guaranteed conductivity.
Fasteners M8 and M10 are from copper, welded products with wood screws 8/100 are from copper and welded products with wood screws 6/50, 8/160 and 8/200 are from stainless steel, A2 grade.
Components for lightning protection and grounding in stainless steel – Inox (Inox V4A)
Used material is stainless steel DIN 1.4301 (AISI 304) with marking N (A2) and stainless steel DIN 1.4404 (AISI 316L) with marking V4A (used for clamps and wire buried in the earth). Fasteners M6, M8, M10 and wood screws are in quality A2 or A4 by type of products.
Components for lightning protection and grounding in Aluminium alloy – AlMgSi
Used material is aluminium alloy AlMgSi, the wires and receiving rods are supplied from material EN AW 6101B. Fasteners M8 and M10 including spring washer are made from stainless steel in quality A2.
Components for installation isolated air-termination system
Isolating rod, which guarantied safe distance from the protected equipment, is made from composite material (GFK), clamping components and fasteners M8 are from hot dip galvanized steel.
