Self-supporting sinusoidal metal profile 19/76 of galvanized or pre-painted and galvanized metal sheets can be used as external cover on sloping roofs in all types of buildings.

 

They are distinguished for:
  • Easy and fast standard mounting
  • Excellent weather and corrosion resistance
  • Very good bearing capacity as a roof profile
  • Excellent water flow due to the profile grooves

 

Produced with:
  • Cover width of 760mm, 836mm, 912mm & 1064mm in various thicknesses of metal sheet
  • in lengths from 1m to 12m, depending on the project

The sinusoidal metal profile with a peak height of 19mm and a step of 76mm is the oldest and most well known cladding profile in the Greek market. Because of its flexibility in the transverse direction, it is easily curved and “embraces” the roof. It is mainly used as a roof covering on roofs with a slope of not less than 10%. It can also be used as a side cover and for the construction of doors. Their characteristic joint ensures excellent fit and water tightness of the profiles.

Characteristic Metal Sheets

Metal Sheets

Different materials in different thicknesses are available for the production of the profiles. The metal sheets available for the production of the profile can be steel, aluminum and stainless steel. The thickness of the metal sheets ranges from 0.40mm up to 1.50mm. Pre-painted and galvanized 0.50mm thick steel sheets are usually used.

Available Coatings and Paints

Classic Polyester paint

Polyester paints are the most common and most economical metal sheet coatings. They are suitable for both external and internal surfaces. With a nominal coating thickness of > 20µm they have a very good resistance to external environmental conditions.

Durable Plastisol Paint

Plastisol coating is very durable to external environment. It belongs to the category of “self-healing” coatings on mechanical damage. With a nominal coating thickness of 200μm it is suitable for outdoor applications where the requirements are high.

High req PVDF paint

PVDF coating is suitable for buildings of architectural applications where the texture and color conservation are important. Also its reaction to fire is excellent because it has limited production of smoke, class S1. The nominal thickness is > 35mm.

Color Coating Options

An extremely large number of color coating options are available. Please refer to our sales department for the available colors (RAL1014 to RAL 9010).

* Weight per unit length was calculated taking into account the nominal thickness 0.50mm of metal sheets and the specific weight of steel 7850 kg / m3 and aluminum 2750 kg / m3.

Connection/Support Options

Sinusoidal profiles 19/76 are fastened to the bearing structure by the standard method of visible anchoring. It is recommended that the fixing should be applied to the peaks and not in the valleys. The profiles are designed to cover roofs with a slope of not less than 10%.

Profiles can be overlapped. The lengths of the profiles must be predetermined so at the point of the overlap will have always a support (purlin). For better sealing it is advisable to use sealants at the joints and overlap points.
