Perforated mounting rails with a continuous hole pattern provide a simple, flexible way to attach cables, pipes and conduits to walls and ceilings. Buisklem's fixing rails are sendzimir galvanized for reliable corrosion resistance, making them suitable for damp environments including HVAC systems, greenhouses and stable installations.
Buisklem offers perforated mounting rails in five sizes from BK1 to BK5, covering light cable management up to heavy pipe fixing applications. The complete range of fixing rail accessories includes support flanges, saddle flanges, angle brackets, rail connectors, slide nuts, clamping claws and connection nuts.

Perforated fixing rails and their accessories are standard components across a wide range of industrial and commercial applications.
In HVAC and plumbing installations, fixing rails support pipe runs along walls and ceilings, with clamping claws and pipe brackets securing individual pipe diameters at regular intervals. The sendzimir galvanized finish handles the humidity and condensation present in mechanical plant rooms.
In greenhouse construction and stable equipment, fixing rails provide a structural mounting backbone for water supply lines, lighting tracks and heating pipes. The continuous hole pattern allows layouts to be adapted as the facility evolves, without re-drilling anchor points.
In fencing, banner and stand construction, angle brackets and rail connectors allow modular frame structures to be assembled and reconfigured quickly. For sporting facilities, the same modular approach supports scoreboard mounts, netting supports and equipment rails.
For HVAC and plumbing installations requiring the full mounting solution, our range of pipe clamps provides complementary solutions alongside the fixing rail accessories.
Buisklem's fixing rails are available in five profiles, designated BK1 through BK5. The BK number refers to the rail channel width and material thickness, which together determine the load capacity and the range of compatible accessories.
Smaller profiles (BK1, BK2) are suited to light applications such as cable management and data conduit routing, where loads per fixing point are low. Medium profiles (BK3) cover the majority of standard HVAC and plumbing installations, supporting pipe brackets and clamping claws for typical pipe diameters.
Larger profiles (BK4, BK5) are specified for heavy pipe runs, structural brackets and applications where the rail spans longer unsupported lengths. When in doubt, specify the next size up: the sendzimir galvanized rails are compatible across the full range of angle brackets, flanges and connectors available in this category.
All sizes are in stock and available for immediate dispatch. Contact Buisklem for project-specific sizing advice.
All Buisklem fixing rails in this category are sendzimir galvanized, a process in which cold-rolled steel strip is continuously passed through a bath of molten zinc, producing a tightly bonded, uniform zinc coating. Compared to standard electrolytic zinc plating, sendzimir galvanizing delivers a thicker coating layer, higher corrosion resistance and better mechanical durability under bending and drilling.
The accessories in this range, including angle brackets, rail connectors, slide nuts and flanges, are zinc-plated (electrolytically galvanized). Zinc plating provides good corrosion resistance for indoor and sheltered outdoor installations and is compatible with the sendzimir galvanized rails in mixed-metal assemblies.
For highly aggressive environments such as coastal installations, chemical plants or permanently submerged applications, contact Buisklem to discuss stainless steel or hot-dip galvanized alternatives from the broader product range.
Installing Buisklem fixing rail accessories follows a straightforward sequence applicable to most mounting configurations.

Fixing rails, also called perforated mounting rails or strut channels, are steel profiles with a continuous hole pattern used to securely attach cables, pipes and piping to walls, ceilings or structures. The holes allow flexible positioning of clamps, brackets and connectors without drilling new holes each time a position changes.
Buisklem supplies fixing rails in five sizes: BK1, BK2, BK3, BK4 and BK5. The size designation determines the rail profile width and load capacity, allowing you to choose the right rail for light cable routing up to heavier pipe installations.
Yes. Buisklem's perforated mounting rails are sendzimir galvanized, a continuous hot-dip galvanizing process that provides excellent corrosion resistance. This makes them suitable for damp environments such as greenhouses, stables and HVAC installations where condensation or moisture is present.
Buisklem offers a complete range of accessories: support flanges (30 and 36 series), saddle flanges, angle brackets (90 degree, 135 degree and 45 degree), rail connectors (straight, 90 degree and T-shape), clamping claws, slide nuts, connection nuts and combi profile holders. All accessories needed for a full installation are available in one range.
A support flange (length variant) mounts the fixing rail parallel to the wall using a slotted base and a vertical attachment piece, providing support along the rail's length. A saddle flange (cross variant) cradles the rail from above using a U-channel bracket, mounting it perpendicular to the support surface. Both types come in 30 and 36 series to match the corresponding rail profile.
Buisklem offers three types of rail connectors: flat connectors (for inline rail extension), 90-degree angle connectors (for corner turns) and T-shaped connectors (for branching layouts). Both 35/36-series and 41-series connectors are available to match the corresponding rail profile, all zinc-plated for corrosion protection.
Angle brackets attach to the fixing rail using slide nuts inserted into the continuous slot of the rail and secured with bolts. Buisklem's angle brackets come in 90-degree, 135-degree and 45-degree versions with 2, 3 or 4 holes, allowing precise structural support for cable trays, secondary rails and frames in any direction. The L-shaped and K-shaped variants cover corner and triangular reinforcement applications.
A slide nut is a rectangular nut that slides into the continuous slot of a fixing rail, allowing accessories such as brackets, flanges and clamps to be positioned anywhere along the rail without drilling. Once in the correct position, tightening the bolt locks the accessory in place. Buisklem supplies slide nuts for 35/36-series and 41-series rails in single-hole and two-hole versions.
Yes. Perforated fixing rails are widely used in cable management systems: cables and conduits are routed along the rail and secured at regular intervals using pipe brackets, clamping claws or cable ties threaded through the holes. The continuous hole pattern allows accessories to be repositioned without drilling, making it easy to adapt the layout as cable routing changes.
Fixing rail systems and accessories are standard components in HVAC and plumbing installations, greenhouse construction, stable equipment, fencing and barrier systems, banner and stand construction, and sporting facilities. Any application that requires secure, adjustable mounting of pipes, cables or structural elements benefits from a perforated rail system with matching accessories.
