A metal plate specifically designed for sandwich panel fastening. Its use is mandatory, as it helps distribute the forces and prevent point deformation when screws are applied, significantly improving the panel's performance against cyclical wind pressures, both positive and negative. Installing the PIASTRINA plate increases the mechanical strength of the panel and ensures uniform load distribution, leading to greater durability and safety in sandwich panel installations.

Used together with structural screws to increase the contact area and transmit more force. Washers, generally magnetic, should be cleaned regularly to avoid the accumulation of drilling debris and ensure proper functioning. 

A clip designed to improve the fixation of panels and corrugated sheets in the ISOCOP roof system. This clip is specifically used to prevent the crest of the panels from sinking, which prevents water and other elements from leaking. With its proper profile, the CAPELLOTO allows for firm and secure panel fixation, enhancing the structural resistance of the roof. 

These are used to fasten various materials. The main advantage of self-drilling screws is that they don't require pre-drilling since they have a drill bit tip that creates the necessary hole as the screw advances. This provides greater precision when joining pieces, although in some cases, a smaller guide hole may be recommended to facilitate screw insertion. Self-drilling screws are suitable for surfaces like plastics, thin-gauge metal sheets, fiber cement, plastic tiles, and fiberglass. However, pre-drilling with a drill bit may be necessary in some cases.

Essential for roofing, they connect and seal the ridges of sheets. Made from durable material, they protect against corrosion and weather. Available in various sizes and finishes, they are easily installed with screws or rivets, offering long-lasting protection and an aesthetic finish.
