Details
The 280 mm GTRW 6.4/7 sandwich panel screw is intended for timber substrates. Its thread is designed to provide a firm connection with timber, limit damage during installation and reduce the risk of loosening. It is used in sandwich panel systems where stability and resistance to loads are required.
The galvanised steel provides corrosion protection for different weather conditions. The galvanised finish helps protect against moisture for indoor and outdoor applications. The 280 mm length suits thicker assemblies where greater penetration is required.
The standard version has a galvanised finish and is available from stock at our branches in Miszewko, Słupsk and Elbląg. Other colours can be supplied to order. The stated lead time for painting is approximately 7 working days.
The GTRW 6.4/7 screw connects sandwich panels to timber. The standard galvanised finish is stocked locally, with colour finishes available for projects requiring a colour match.

The very friendly ladies in the shop advised us and helped with our purchase. There is no need to worry about calculating the materials required — they know it inside out. I sincerely recommend them. We will certainly come back if we need anything else. A very wide range of goods is available immediately.

Hello, I bought PIR boards some time ago and, despite having to travel 400 km, I do not regret it at all. Professional service, very good communication and reasonable prices. I sincerely recommend them — it is worth it. They care about keeping the customer happy. I will certainly use them again despite the distance. Best wishes.

Highly recommended. I bought T7 sheet metal from stock and it was delivered the same day, for which I am very grateful. Very courteous, friendly and professional service. Thank you again, best wishes, and I recommend this building materials yard to everyone. 😊

Hassle-free service. They did everything as I wanted. My customer adviser, Patrycja, was very kind. I definitely recommend them, especially as the sandwich panel comes under the thermal renovation programme.

A friendly company with positive people. The sandwich panels were unloaded immediately. The forklift driver knows what he is doing. Before you reach the site there is a petrol station with a nice café and parking for a few vehicles at the back.

I went yesterday for a few sheets for my garage. There is a huge choice of colours, thicknesses and lengths in the yard. Thank you to Andrzej and Tomasz, who quickly work out what is needed and give advice. A pleasant atmosphere and professional service. Highly recommended.
