Stainless steel screws in tunnel and bridge construction

Our mission in solar technology                             Reliable fastener technology for solar systems

Stability and reliability in the supply chain are crucial in the dynamic renewable energy industry, especially when it comes to solar technology. As a wholesaler for stainless steel screws and other fasteners, we offer a reliable supply of high-quality products for solar assembly systems directly from stock. In this way, we give our customers a high level of availability for the products they need, as well as the flexibility to be able to complete their projects on time.

Wide range of products to meet every need

Our product range includes a wide selection of products specifically designed for use in solar and photovoltaic systems:

  • Thin sheet metal screws with ETA approval
  • Hangar bolts (tested design)
  • Hammer-head screws
  • Roof hooks (tested design)
  • Wood screws with ETA approval
  • Other specialized fasteners such as nuts, washers and slot nuts

In addition, we offer our customers custom solutions for their order, such as surface coating and parts made according to specification in order to meet specific requirements of our customers.

Quality standards and certifications

Market demands and requirements are increasing. Certificates and approvals, and not merely prices, are increasingly decisive for purchase decisions. As a DIN EN ISO 9001 certified company, we cannot and do not want to ever compromise on quality.

There is a reason we are listed in general building inspectorate approval Z-30.3-6 from April 20, 2022 of the Deutsches Institut für Bautechnik (DIBt) in the field of fasteners for stainless steels.

Corrosion resistance                                                                    Adapted materials selection

Choosing the right material is crucial for the durability and safety of solar systems.

Notice:                Complaints about a solar system constructed with incorrect materials can quickly lead to a loss of product liability insurance coverage!

CRC stands for corrosion resistance class. The following are used in solar technology:

  • CRC II (1.4301 or 1.4567): Ideal for installations in rural and urban areas with a low to medium exposure risk.
  • CRC III (1.4401 or 1.4571): Recommended for applications in maritime regions and other environments with an increased risk of corrosion.

Where our products are used

Our screws and fastening systems are ideal for a wide range of applications in the solar sector, such as:

  1. Roof systems for flat and pitched roofs, as well as solar carports
  2. Facade systems, especially for solar facades
  3. Free-standing systems such as agrivoltaic systems, tracker systems and elevation systems
