Fasteners for the solar sector: solar panel frames and trackers

When building any kind of photovoltaic structure, it is important to use high-quality components and accessories to ensure top performance and maximum durability. This means that it is key to select the right fasteners to guarantee a robust and long-lasting installation.

At CHAVESBAO, we offer a range of standard carbon steel fasteners for both fixed and moving structures, designed for use by manufacturers of both static frames and solar trackers.

Fasteners for solar panels: frames and trackers

Our range of standard carbon steel structural fasteners, (which covers grades 8, 10, 8.8, 10.9, 12.9, HV 140, HV 160, HV 200 and HV 300) will guarantee that your solar panel structure is robust and durable. We also offer A2 and A4 stainless steel fasteners for attaching the panel to the frame, ensuring resistance to corrosion. The standards used on fixed or moving structures: DIN 931, DIN 933, DIN 6921, EN 15048, DIN 912, DIN 934, DIN 985, DIN 6923, DIN 125, DIN 9021, NFE 25513, DIN 6798-A.

En CHAVESBAO disponemos de una amplia selección de tornillería estandarizada para la fabricación de componentes de aerogeneradores o cualquier otro elemento del sector eólico.

Tornillería estandarizada para aerogeneradores y turbinas eólicas

El uso de tornillos estandarizados garantiza la calidad y seguridad de los productos empleados en la fabricación de los componentes dentro del sector eólico. En nuestro catálogo encontrarás una gama de tornillería que se ajusta a las diferentes Normas DIN que hacen referencia a la composición y estructura de cada uno de los productos:

Tornillos hexagonales

Los tornillos hexagonales aptos para la fabricación de aerogeneradores están fabricados según las Normas DIN 931 y DIN 933 que aplican a su estructura. En el primer caso se componen de cabeza hexagonal y cuerpo cilíndrico con media rosca. Además, los tornillos DIN 931 están disponibles en calidad 8.8 y 10.9. Los tornillos hexagonales DIN 933 incluyen también cabeza hexagonal, pero, a diferencia de los primeros, en estos el cuerpo está totalmente roscado.

Tuercas hexagonales

Las tuercas hexagonales para la fabricación de aerogeneradores y turbinas eólicas se ajustan a la Norma DIN 934 que hace referencia a la composición y estructura de las mismas. Este tipo de tuercas son las más comunes en el mercado y en nuestro catálogo podrás encontrar una amplia selección de productos en calidad 8 y calidad 10 -con diferentes grados de resistencia- que se adaptan según el tipo de componente a fabricar.

Arandelas planas

Las arandelas planas se ajustan a las Normas DIN 125 y DIN 9021. Las arandelas planas DIN 125 se utilizan comúnmente en una amplia variedad de aplicaciones. Sin embargo, las arandelas DIN 9021 son más anchas que las anteriores proporcionando una mayor superficie para la distribución de la carga.
