Our ordering process - How we work
We supply materials based on clear, detailed order information to minimise errors and ensure accuracy. Below, you'll find a summary of how we work with clients, what we supply, and the steps involved in placing an order.

Discovering The Metals & Products
STS Panels® & STS Panels® are premium versions of the snap-together standing seam panel and traditonal standing seam panel systems — featuring hidden fixings, high-quality metals, and strong warranty options. Widely chosen for both appearance and technical performance.
We can assist during early-stage enquiries by offering provisional pricing based on defined components. However, accurate quotations always depend on receiving a clear, confirmed list of required items, lengths, quantities, and any relevant production drawings.
While basic drawings may help with initial estimates, all details must be checked and confirmed by the customer before an order is placed. It is the customer’s responsibility to understand what they need to order.
Our pricing reflects both the size of the order and the amount of preparatory work required. The more complete and accurate your information, the faster we can quote — and the better the pricing is likely to be.

Finalising Order Details
Once a provisional quote has been reviewed and accepted, we move to finalise the order. This involves checking key dimensions, confirming any flashing drawings, and verifying quantities to ensure the order is production-ready.
We always send physical metal samples to confirm the finish. Please note that while most samples arrive within a few days, delays may occur. Customers should notify us if samples are not received within one week.
Once the finish is confirmed and all order details are signed off, we issue a proforma invoice. Payment is accepted by bank transfer only.
Upon receipt of payment, your order is entered into the production queue and a provisional dispatch date is issued. This marks the start of the lead time and ensures timely fabrication and delivery.
If you're unsure where to start but have a live project requiring materials soon, it may be worth using our Provisional Schedule service. For £150 + VAT, we compile a detailed item list based on your drawings and project details. This helps establish what you'll need to order and ensures your quote is based on real components, not just m² estimates. If the project proceeds and an order is placed, this fee is fully refunded.
Customers should note: that delivery does not include offloading facilities unless a Moffett is ordered at an additional cost. A suitable offloading area must be available on-site, whether for manual unloading or using a forklift if one is available.

Order Fulfilment
Once your order has been delivered, it's essential to check the goods immediately and report any damage to the driver before they leave. Photo evidence is required to process any damage claims.
If additional materials are needed later—due to under-ordering or site issues—they may be subject to standard lead times. That said, we always do our best to dispatch extras quickly to minimise disruption to your build.
Fortunately, the vast majority of deliveries arrive in perfect condition, thanks to careful packing and a detailed ordering process designed to avoid errors from the start.
We’re always happy to feature completed projects, so if you're proud of the result, feel free to share some photos—we may include them in our example gallery.

Product Over View - For the self builder?
STS Panels® is an ideal choice for simple projects. However, for more complex installations, some training is recommended.
While joining panels is easier than with traditional standing seam systems, it is important to note that not everything simply snaps together. Some cutting and folding of metal will always be required during installation. Although Merlin Metals does not provide training directly, we assist clients by clarifying key points and referring them to training if their project requires it.
Unlike other systems that secure flashings by driving fixings through the metal, STS Panels® are more closely related to traditional standing seam than industrial cladding. This means it avoids fixings penetrating the metal. Instead, flashings are folded to liner flashings, eliminating visible fixings and creating a more premium, seamless look.
- Eaves. This flashing goes into the gutter, the roof panels are folded around this to secure the eaves line.
- Verge. Panels may need cutting at the verge side and an upstand turning 90 degrees for the verge flashing to engage with.
- Ridge. The top of roof panel need folding up slightly and the ridge flashing requires folding to the ridge liner.
- Roof Lights. Custom roof light flashing kits require accurate planning.
- Wall Panels. Require a base flashing which the panels are folded around to secure the panels so no fixings through the metal are needed.
- Windows & Doors. Attention should be given to the layout and how the seams land so the correct flashings or panel folding can be planned.
