S18
S18 has a wide range of uses both for the roof and interior and exterior walls such as covering household annexes, vertical closures (walls), delimitations, gate closures, fences, silos
SMART BENEFITS
SMART S18 Corrugated Sheet is a sinusoidal sheet metal profile designed for roofing, facades, or fencing applications, characterized by an 18 mm wave height and a corrugated design with rounded lines. Unlike trapezoidal profiles, the sinusoidal shape gives the panels a more fluid and decorative appearance, suitable for a wide range of applications.
Thanks to its versatility, the S18 corrugated sheet can be used for covering annex buildings, sheds, or canopies, as well as for vertical cladding, fences, gates, or property delimitations. The profile is suitable both for exterior applications and interior cladding, where the corrugated texture can create an interesting decorative effect.
The sinusoidal profile design provides a balance between structural resistance and aesthetics, making it a suitable solution for projects where both durability and a distinctive surface appearance are desired.
The panels can be installed vertically or horizontally when used for wall or facade cladding, depending on the desired architectural solution.
SMART S18 corrugated sheet is manufactured from pre-painted galvanized steel sheet, available in glossy polyester and matt polyester finishes, as well as special decorative finishes. The range includes variants that imitate wood texture, such as Walnut and Golden Oak, but also decorative finishes such as Camouflage or Apple Tree, inspired by the appearance of hedge foliage.
Through the combination of the sinusoidal profile, versatile use, and easy installation, SMART S18 corrugated sheet represents a practical solution for creating roofs, cladding systems, or fencing made from corrugated sheet metal.

SMART ACCESSORIES
STRAIGHT CREST H12
STRAIGHT CREST H12
Used to close the intersection between 2 roof slopes, straight or angle-mounted.
BORDER BAR H12
BORDER BAR H12
It is used to close the roof on the side. Designed specifically for the H12 and H12Plus, it also works for the H6. In the case of corrugated sheets with a higher crease, it is recommended to use accessories with the same role from the metal tile.
BORDER BAR GRADE
BORDER BAR GRADE
It is installed at the edge of the roof, after installing the gutter grade and before installing the roof tile panels. Its role is to gather water infiltrations that may occur due to lack of perpendicularity between the edge of the roof and the gutter edge.
GUTTER GRADE H12
GUTTER GRADE H12
It is installed on the wooden structure intended for fastening the rainwater collection system, after the system has been mounted but before applying the vapor barrier membrane. During installation, a 5 cm overlap must be created over the gutter. The role of the gutter apron is to direct the water flowing from the roof into the gutter and to protect the wooden structure of the roof even when a rainwater drainage system is not installed.
INNER CORNER PROFILE
INNER CORNER PROFILE
Joins two perpendicular walls on the inside corner.
OUTER CORNER PROFILE
OUTER CORNER PROFILE
Joins two perpendicular walls in on the outside.
LONGITUDINAL JOIN PROFILE
LONGITUDINAL JOIN PROFILE
Used for fixing and ensuring the connection between constructive elements, serving as a transition piece where components are installed over another support.
FENCE COVER PROFILE 70
FENCE COVER PROFILE 70
Used for H12 and H12+ corrugated sheets when they are installed as fencing. Its role is to protect the exposed edge of the trapezoidal panel and prevent premature corrosion.
COVER PROFILE 74
COVER PROFILE 74
It can be used to fix various roof elements onto wall surfaces, providing protection and securing the constructive components.
FENCE CREST 220
FENCE CREST 220
It is positioned at the top of a fence made of corrugated sheet panels and serves to prevent their premature corrosion. The unfolded width is 220 mm.
START PROFILE TR45
START PROFILE TR45
It is used for the installation of corrugated sheet metal on the façade, and can be used in several situations: starting profile (it is installed in the boulder at the base of the wall, above the windows) - offers a straight starting base or as pressor or termination profile. It is used in the upper area of the wall to mask the cut of the panels or to press the panel towards the wall.
BORDER BAR TR45
BORDER BAR TR45
It is used when closing the edge roof. It is installed over the roof and is suitable for corrugated roofs with a pitch height of 35-50 mm.
CREST TYPE BORDER BAR TR45
CREST TYPE BORDER BAR TR45
It is used to close the upper ridge area, in case a roof slope intersects one of the vertical building walls. Specifically designed for TR45 corrugated sheets.
FIRE WALL BAR TR45
FIRE WALL BAR TR45
It is used on the edges of the roof to ensure the collection of rainwater that infiltrates accidentally.
It is imperative to use it especially if the angle made by the edge of the roof with the eaves is open / >90° / obtuse.
SIMPLE STRAIGHT CREST TR45
SIMPLE STRAIGHT CREST TR45
It is used to close the intersection between 2 slopes of the roof, in a straight position or in an inclined position.
BLIND WALL ANGLE
BLIND WALL ANGLE
It is used at the intersection between a wall / blind wall and a roof slope, at a blunt angle. The slope angle starts at the intersection with the wall. The blind wall angle is mounted in the wall.
