Fixing screw for sandwich panels — 6.3 × 228 mm, for timber, zinc-coated

Sandwich panel thickness is immediately visible, but its connection to the structure also depends on what lies beneath it. Screws must suit the entire arrangement: panel, support and service conditions. SteelProfil helps select fasteners for walls and roofs, allowing installation to be planned as carefully as the core material and facing colour.

The screw must be long enough to pass through the components being fixed and achieve adequate anchorage. The supporting material also matters: steel, timber and concrete require suitable versions. A correctly selected fastener helps the team install the panels in accordance with the documentation. We help compare options using the panel thickness and information about the building structure.

Sandwich panel fasteners are designed for the particular requirements of lightweight cladding. Depending on the product, they have an appropriate thread arrangement, tip and washer. Their purpose is to secure the panel without inadvertently deforming the facing. Suitable tools and controlled tightening pressure allow the fastener to perform as intended while maintaining the appearance of the finished surface.

The EPDM seal on the washer helps keep the fixing point watertight. This elastomer’s resistance to UV, ozone and weathering matters in outdoor applications. It should be compressed as specified for the particular screw. This practical detail combines mechanical fastening with suitable protection where the fixing passes through the facing.

The screw’s particular coating protects it against corrosion. On zinc-coated versions, the zinc layer performs this function; other protective systems are also available. Selection should suit the environment in which the entire cladding operates. Consider this when choosing the panels so that the durability of the fixings and facing finish is planned for the same service conditions.

SteelProfil offers promotional deals and competitive prices to help you assemble the cladding package economically. Some materials are available from stock; we check the required screw size together with the quantity. Preparing a schedule from the installation design is useful, because edge zones and other areas may require different fixing layouts.

The availability of panels and insulation in first and second grades gives customers more ways to match their budget. Fasteners for the selected batch are still chosen according to technical requirements, irrespective of its commercial grade. This combines an economical cladding purchase with suitable installation. We also help include the accessories needed for flashings and joints between adjoining components.

The owner of a completed hall rarely examines each screw individually, but benefits from a properly installed fastening system. An even facing and orderly fixing layout contribute to the building’s appearance. Send us the panel and structure specifications so we can identify a suitable version. This helps complete procurement with efficient installation and the everyday function of the roof and walls in mind.
