Mechanically seamed S.Falz INDUSTRIAL
The key feature of the system is the connection of panels to each other using a double standing seam lock directly on site. Such a connection creates a monolithic coating without a single through-hole, which is the main technological advantage and guarantees absolute watertightness.
• The use of electric seaming machines allows quick and high-quality closure of large roof volumes. The possibility of using self-locking (click-seam) or single seam on sites with sufficient roof slope accelerates the process, turning it into assembly of a constructor.
Metal thickness: 0.7–1.0 mm (choice of thickness depends on roof type, rafter spacing, and snow load).
Usable width: determined by seam profile type (standard sizes — 350–1500 mm).
• Shopping centres and hypermarkets.
• Industrial workshops and production buildings.
• Sports complexes and ice arenas.
• Multi-apartment residential buildings with flat and sloped roofs.
What is mechanically seamed and why is it so popular
Standing seam is a special method of joining metal sheets or panels into a single watertight surface. The connection is made without through-holes (which eliminates leaks) and does not require welding. Standing seam roofing and facades have been known since the 19th century, but modern technologies and materials have made them even more reliable and diverse.
How standing seam connection works
Two adjacent metal sheets (panels) are joined by bending their edges. Standing seam extends above the roof plane, lying seam is in the same plane. For industrial facilities and buildings with large spans, double standing seam is most often used — the most watertight and durable type of connection.
Main advantages of mechanically seamed
-
Absolute watertightness. No through-holes — no leaks. Water cannot penetrate under the roof.
-
Durability. Service life of standing seam roofing from copper or stainless steel — 80–100 years, from steel with polymer coating — 30–50 years.
-
Load resistance. Standing seam roofing withstands snow and wind loads without deformation.
-
Aesthetics. Clear lines of standing seam give the building a modern, "European" appearance. Suitable for any architectural styles.
-
Repairability. When one sheet is damaged, it can be replaced without disassembling the entire roof.
Types of industrial standing seam and where they are used
Standing seam
Sheet edges are bent upward, forming a vertical ridge above the roof plane.
Application: sloped roofs with slope from 7–10°, facades, industrial buildings.
Pros: maximum watertightness, striking appearance.
Recommendation: the most popular type for roofs and ventilated facades.
Lying seam
The connection is in the same plane as the roof (edges are bent horizontally).
Application: mainly for joining sheets along the slope length (paired with standing seam).
Pros: smooth surface, convenient for walking on the roof.
Single and double seam
-
Single (one bend). Used on non-critical areas, for non-critical structures.
-
Double (two consecutive bends). The most watertight and reliable type. Recommended for critical facilities: residential buildings, office centres, industrial buildings, hangars.
Recommendation: for residential and commercial roofing, choose only double standing seam.
Trapezoidal seam
The ridge has not a rectangular, but a trapezoidal shape. More rigid construction.
Application: regions with high snow loads, industrial roofing.
Materials for industrial standing seam
The choice of material affects the appearance, durability, and cost of standing seam roofing or facades.
| Material | Service life | Aesthetics | Price | Recommendation |
|---|---|---|---|---|
| Galvanised steel with coating | 30–50 years | Any RAL colour, matte or gloss | Low | Budget option for warehouses, hangars |
| Stainless steel | 50–80 years | Silvery, matte or mirror finish | High | For prestigious buildings, aggressive environment |
| Copper | 80–100 years | Pink-golden → brown → green patina | Very high | For temples, mansions, historic buildings |
| Aluminium | 40–60 years | Silvery, can be painted | Medium | Lightweight, rust-free, for any buildings |
| Brass | 50–80 years | Golden, ages with noble patina | High | Elite projects, boutiques, exhibition halls |
Technology of industrial standing seam installation
Professional installation is the key to watertightness and longevity.
1. Preparation of the substrate
-
Sheathing (wooden or metal) with spacing calculated for metal thickness and snow loads.
-
Waterproofing and vapour barrier (under roofing).
-
Counter-battens to create ventilation gap.
2. Manufacturing of panels (blanks)
At the factory or on site, sheets of the required length (panels) are cut from coil strip. Edges are prepared for seaming (edges are bent).
3. Laying and joining
-
Panels are laid on sheathing.
-
Clips (special fasteners) secure them to the sheathing.
-
Seam connections are made manually (with a mallet and straightedge) or with an electromechanical seaming machine. The second option is faster and higher quality.
4. Installation of trim elements
Ridges, valleys, wall penetrations, parapets, snow guards — all are manufactured from the same material and installed with watertightness compliance.
Why you should buy industrial standing seam from a manufacturer
If you decide to order and buy industrial standing seam for roofing and building facades, working directly with the manufacturer offers several important advantages.
Prices from the manufacturer
Without distributor and construction supermarket markups. Manufacturer prices for industrial standing seam for roofing and facade cladding per m² in Moscow are 15–25% lower than market prices.
Quality control of metal and seam
The manufacturer is responsible for the chemical composition of steel, thickness of zinc coating or polymer layer, as well as the accuracy of seam lock geometry.
Any panel length
Standard sheets have limited length (up to 6–8 m). The manufacturer can make panels up to 16–20 m long, which minimizes the number of transverse (lying) seams. This increases watertightness.

Frequently asked questions
1. How does double standing seam differ from single?
Double seam has two consecutive bends, creating a tighter and more watertight connection. It withstands higher wind loads and is less susceptible to loss of seal over time. For residential and commercial buildings, only double seam is recommended.
2. Can seam be used on facades?
Yes. Standing seam on facades (vertical or horizontal placement) creates a clear, modern pattern. Aluminium and stainless steel seam is especially popular for ventilated facades of business centres and private homes.
3. What roof slope is needed for seam?
The minimum slope for standing seam is 7–10°. With a smaller slope, there is a risk of water stagnation and leaks, even with double seam. For roofs with a slope of less than 7°, a solid substrate and special sealants are used.
4. Is special equipment needed for installation?
For a one-time small roof, seam can be made manually (with a mallet and straightedge). For industrial facilities and large areas, electromechanical seaming machines are used, which ensure a perfectly even lock along the entire length.
5. How to repair standing seam roofing?
When one element (panel) is damaged, it can be replaced without disassembling the entire roof. The damaged sheet is cut along the seam, removed, and a new panel is installed in its place and the seam is rolled. Difficulty depends on seam type and access.
