Galvanized steel Eurofala / Ekofala screw, timber, dimensions 6.5 × 132 mm

Corrugated fibre cement needs fixing points suited to its shape and movement. Screws for Eurofala and Ekofala sheets help connect the covering to supports and seal the penetrations through its surface. Specialist solutions make successive sheets easier to install while maintaining a regular roof geometry.

Fibre-cement systems specify fixing points on the appropriate corrugation crests. This position uses the covering’s shape and places the fastener penetration where the manufacturer intends. Screw length accounts for profile height and the required embedment in the support. The sheet can therefore be secured through its three-dimensional form without crushing the corrugation. Repeated fixing positions guide subsequent rows and keep a roof with many identical elements orderly.

The pressure-distributing and sealing assembly spreads the load around the hole and helps protect it from water. The flexible seal conforms to the sheet surface, combining fastening with weather protection. Fibre cement needs the specified movement clearance, so a system intended for this covering is important. Such a fastener creates a repeatable detail without adding arbitrary washers. All components work together to hold the sheet and close the penetration through the roof.

Buildings with corrugated sheets may have timber battens or steel purlins. Screws matched to these substrates allow similar roofing materials on different structures. This is useful when renovating outbuildings or adding a new hall section. The tip and thread serve the support, while the outer assembly works with the sheet. Selecting the fixing therefore allows fibre cement to be used in various arrangements instead of limiting it to one frame type. This flexibility is useful on farms with several buildings: a similar roof form can appear on a cattle shed, shelter and warehouse, each with fixings matched to its own supports.

In systems such as Quick Fix, special wings prepare the hole in the sheet as the fastener is installed. This avoids the separate pre-drilling required by other solutions and helps with large numbers of fixings. It is a feature of a particular system, which must be selected according to the sheet manufacturer’s requirements. A suitable coating or stainless steel helps match the fastener to its environment. The complete assembly can then offer both convenient installation and protection of the fixing point during the covering’s service life.

At SteelProfil, we offer fibre-cement roofing screws at attractive prices. Selected materials are available from stock, with promotions and first- and second-grade options across the wider construction range. Check solutions for your sheet and supporting material to install the fixings efficiently on a new or renewed roof.
