Application in a photovoltaic installation
The roof mount is the only point where the photovoltaic installation contacts the building structure, and the only point through which the load is transferred to the truss. The choice of roofing material determines the roof's tightness—it attaches differently to ceramic tiles, to seam metal, and to shingles.
When installing a tile, the bracket must pass under it without tension or lifting adjacent roofing elements. The adjustable bracket allows for on-site adjustments, shortening installation times on roofs with uneven battens.
Roof bracket double-threaded screw m10×300 - what to pay attention to when choosing
When purchasing this item, check three things: compatibility with existing equipment on site, site conditions, and the quantity needed for the entire project. Photovoltaic system components operate outdoors for several years, in full sunlight and with fluctuating temperatures, so the choice of material and workmanship is crucial to the durability of the entire installation.
If you are collecting material for a specific installation, it is more convenient to take everything from one delivery - the remaining items from the same group can be found in the assembly structures category , and all excess stock in the Stock category.
Where does this stuff come from?
We sell inventory left over from closed projects and deliveries. The merchandise is brand new and covered by the same returns and refunds policy as the rest of our offerings. The only difference is that quantities are limited and will not be restocked—once the stock is depleted, the item will be removed from the store.
Minimum order and price calculation method
We sell this item from 5 pieces. The price listed for each item is for a single item, so the minimum order value is 5 times that amount. This threshold is based on inventory accounting: for small items, the time required to deduct and pack several items costs more than the item itself. However, when ordering a full package, this cost is spread across all items, allowing the unit price to drop that low.
The quantity ordered increases incrementally in the cart, so you can't accidentally place an order below the threshold. Above the threshold, you can purchase any number of items until stocks last—which is limited to what's left in stock.
Delivery and pickup
Orders are shipped from our warehouse. Shipping costs depend on size and weight—small items are shipped as a parcel, while items longer than a standard parcel require pallet shipping, which is visible in the shopping cart after adding items. For orders with multiple items, shipping costs are calculated once for the entire shipment, so collecting the materials for a single order is cheaper than shipping several items separately.
You can also collect the goods in person at our warehouse in Bytomiu — pickup is free. For low-value items, this is often the most reasonable option, as shipping costs can be as high as the order itself. It's worth confirming availability before arrival, especially for last-minute items.
