Sandwich cladding fixing, 6.3 × 173 mm, for timber, zinc-coated

Sandwich panels form extensive walls and roofs on industrial buildings. Their stable connection to the structure depends on correctly selected fixings. Each fastener must suit panel thickness and the supporting material. Sandwich panel screws provide the connection intended for this type of envelope. SteelProfil can select them together with roof or wall panels and the necessary finishing components.

Selection accounts for the facings and required structural anchorage as well as core thickness. Products are available for specified steel or timber supports and other substrates identified by the manufacturer. Correct selection helps create a connection that follows the design and provides a basis for efficient installation of successive panels.

The screw is designed to pass through a layered element and retain it on its support. Depending on the version, thread sections and point characteristics are important. The fastener must also suit exposed fixing or the connection within the panel joint. We select the product for the specific assembly so that its construction assists the installation team.

Cladding fixings use washers with EPDM, a rubber resistant to UV, ozone and weather. With suitable clamping pressure, the seal helps protect the interface where the screw passes through the facing. An appropriate corrosion-resistant coating, including zinc on relevant variants, protects the fastener itself. Protection is selected for the service environment.

Careful installation preserves the shape of the washer and facing. Fixing positions and quantities depend on loads, panel type and support arrangement. Prior selection allows the crew to repeat a consistent installation method. This is particularly useful on large walls or roof slopes where organisation determines the speed of enclosing the structure.

Suitable fixings matter in warehouses, workshops, retail premises and agricultural buildings. Service conditions can differ in each case. Establish the coating type, required accessories and appearance of exposed heads. Consistent details create a neat façade, while correctly selected components fulfil the structural task.

SteelProfil can supply fixings together with the building envelope. Selected materials are available from stock, and the panel range includes grades 1 and 2. Promotions and favourable prices help organise the complete purchase. We select screws according to their documentation and application conditions so that they match the chosen panel type.

Send us panel thickness, support material and the fixing arrangement from the design. We will check suitable variants and quantities. Ordering small components before the main cladding delivery helps installation start on schedule. The structure can then receive complete walls and a roof with consistent connections throughout. Separate schedules for walls and roof slopes also make it easier to issue fixings to the crew.
