METAL COILS FOR STANDING SEAM ROOFING COMAX FALC

The proven method of traditional double standing seam is now again a very popular and increasingly used method of covering all types of roofs and structures. Thanks to modern architecture, the covering of pitched roofs and facades becomes a very aesthetic solution with emphasis on functional prerequisites even in the most demanding conditions.


ALUMINIUM CORE - COMAX FALC

Aluminium as a very light metal is widely used mainly in the form of alloys in the construction, automotive and aerospace industries. Magnesium and manganese alloyed material is particularly suitable to produce aluminium groove coverings. This metallurgical process guarantees increased vibration resistance and good fracture toughness while reducing the thermal expansion of this material. We can simply say that the material for COMAX FALC with aluminium core with a thickness of 0.7 mm from AlMn1Mg0.5 alloy designed for single and double standing seams, does not break, does not crack and is ideally ductile for complex details. Aluminium alloys are the most widely used metal construction materials worldwide for their perfect properties. An alloy with a precise ratio of trace elements AlMn1Mg0,5 is a hardened material with high weather resistance and ideal corrosion resistance. It could be said that the aluminium roofing is due to its durability predestined for roofs of all types and shapes to lower as well as higher altitudes.

STEEL CORE - COMAX FALC

On the other hand, COMAX FALC with steel core and full-fledged galvanizing of 275 g/m², complemented by a high-quality finish coating, also meets the demands of modern construction or reconstruction of pitched roofs as an alternative to covering pitched roofs with lower purchase costs and a lifetime guarantee of up to 30 years. The main advantage of this material with a softened steel core for a standing seam is a lower thermal expansion, whereby the sheet changes its volume considerably less as a result of temperature changes. A very important factor affecting the lifetime of the seamed sheet is the frequent underestimation of material expansion or poor application of suitable sliding and fixed clips for fitting COMAX FALC 25. This is often accompanied by undesirable corrugations, unpleasant noise and, later also low anchoring strength of the roofing in the wooden underlayer. When choosing a suitable installation company for fitting roof and facade sheet metal, pay attention to references and craftsmanship in this industry. The method of securing the expansion is specified in the installation instructions for COMAX FALC 25.

ROOFING SUITABLE FOR USE FROM 4 ° ROOF PITCH


EXTRA WATERTIGHTNESS OF THE ROOFING COMAX FALC WITH MAINTENANCE-FREE FINISH

Many of you will remember the possibilities and techniques of roofing seams from the past. It was mainly a technique of covering on the principle of standing seam. The most commonly used materials were metal sheet of 2000 mm x 1000 mm, in natural mill finish, or with a single-layer coating of paint using a roller or brush directly on the roof.



In most cases, these roofing types required regular maintenance, associated with coating, or investment in copper. The roof cladding with a cover of 1,000 mm to 1,500 mm wide seamed metal sheet was leaky at the joints, noisy in bad weather thanks to the width of the sheets and it could not be safely fitted to a full-supported surface. Fortunately, these limited production and assembly options of seamed sheet metal roofing for family houses are an issue of the past.

A new system of continuous coating of metal coils intended for folded connection of roofing with double standing seam brings new possibilities. COMAX FALC with a cover width of 520 mm for aluminium and 540 mm for steel, represents a solution for every roof with an emphasis on functionality and colour fastness. COMAX® ROOFS delivers a colourful, diverse solution for covering roofs of all kinds of buildings and structures with a slope of 4 °, which will reliably protect the home for future generations.

THERMAL EXPANSION OF MATERIALS INTENDED FOR STANDING SEAM

As with other building materials, the influence of thermal expansion on metal roofing sheets is influenced by the ambient temperature. It changes during the year and may vary from -20 ° to 80 ° C. As a result of these temperature changes, the volume of the materials used varies considerably, thereby the length of COMAX FALC sheetsincreases or decreases. For steel coils intended for folded connections, the expansion of the material is significantly lower than for COMAX FALC aluminium alloys. When fitting, make sure that the fixed and sliding clips are positioned correctly. In order to prevent undesirable corrugations, which is often accompanied by a noticeable noise of the roofing, it is necessary to follow the installation procedures and valid standards during assembly.

COMAX FALC AS A ROOF COVERING WITH EXCELLENT WATER TIGHTNESS

Sheet metal intended for COMAX FALC standing seam meet the highest demands for watertightness and lifetime of roofing. Their adaptability in detail and tightness in connection of the roofing sheets overcome the boundary of flat roofs with usability as low as 4 ° of the roof pitch with additional waterproofing. All transverse joints of the sheet, interruption in the surface, expansion steps and roof penetrations are key aspects to be considered. At the same time, these also include the suitably selected and precisely made connection of these details, depending on the roof pitch, ranging from the simple seams of the sheets at the high slope, to the downfall and double horizontal seaming of the COMAX FALC roofing for extreme low pitches and complex details.

FLAT SHEET METAL ROOFING IS ONE OF THE OLDEST METHODS OF COVERING PITCHED ROOFS

The roofing sheet has been accompanying mankind for over two millennia. During this time, this material has undergone many changes and improvements. Its expansion and popularity for covering pitched roofs has increased as a result of its excellent technical and functional features and financial availability for the general public. Modern options for protective coatings with COIL COATING method give the seamed sheet a unique aesthetic look and also significantly extend its life. The metal sheets intended for seams folding by the COMAX® ROOF manufacturer meet the highest demands placed on the durability and functionality of the roofing.


COMAX FALC, AlMn1Mg0,5 - PVDF, PUR/PA


The aluminium alloy designed for production of coated metal coils for standing seam folding, is ideally ductile due to aluminium alloys and meets the highest demands for T bends without cracking even under extreme loads.

Coated metal coils from COMAX® ROOF designed for standing seam are of high quality, aesthetic and have a long life and colour stability. PVDF, PUR / PA (polyurethane / polyamide) surface finishes guarantee the highest quality of this material delivered to the European market. Sheets to produce our roofing systems combine the highest corrosion resistance, UV resistance as well as resistance to mechanical damage. With a protective topcoat of up to 50 µm, our roofing systems can withstand even the most demanding conditions, such as in chemical environments, mountain and coastal areas.

Your roof will have a unique look with a roof covering weight of up to 20 times lower than conventional ceramic or concrete tiles. A classic 200 m2 gabled roof will typically weigh 50 kg / m² with a total weight of 10 tons when laying a ceramic or concrete tile roofing. In contrast, aluminium seamed roofing COMAX FALC - 2.1 kg/m², will reach a weight of only 0.5 tons on the same roof. Low weight is a huge financial advantage for transporting the roofing to the construction site. It reduces the total cost of the timber used to make the roof structure and at the same time saves the cost of fitting the roofing by a specialized company.



PRODUCTION OF COMAX FALC ROOFING

Production of COMAX FALC roofing is tailored to each roof according to the processed and enclosed layout plan. The maximum production length of the elements for handling and transportation is 8000 mm. COMAX ROOFS also offers the OPTION OF DELIVERING METAL IN A COIL FOR PROFILING ON THE CONSTRUCTION SITE, where the production of sheets can be extended up to 15,000 mm using corresponding clips with a longer slide track.
