TR18
TR18 distinguishes by the ribbed profiles, closely spaced, intended to ensure increased mechanical resistance, as well as to define the aesthetics of this product
SMART BENEFITS
SMART TR18 Corrugated Sheet is a robust corrugated sheet metal profile designed for roofing, facades, or fencing applications, characterized by an 18 mm rib height, which provides greater structural rigidity compared to lower-profile corrugations.
The profile design includes closely spaced reinforced ribs, which contribute both to the mechanical resistance of the panel and to defining a modern surface appearance. Thanks to this configuration, TR18 corrugated sheet is suitable for applications where greater panel stability is required or for larger roofing surfaces.
The profile can be used for a wide range of applications, including roofing for household annexes, garages, canopies, or lightweight constructions, as well as facade cladding, fences, or delimitations. Due to its superior rigidity, TR18 corrugated roofing sheet is a frequent choice when a more stable profile is desired compared to lower corrugation variants.
The panels can be installed vertically or horizontally when used as corrugated sheet for facades, offering flexibility in cladding execution and the possibility of achieving different architectural effects.
The product is also available in a negative corrugation version, frequently used for vertical cladding or for finishing the area under the eaves (soffit), where the panels can create an orderly appearance similar to metal paneling.
SMART TR18 corrugated sheet is manufactured from pre-painted galvanized steel sheet, available in glossy polyester and matt polyester finishes.
Through the combination of profile rigidity, versatile use, and simple installation, SMART TR18 corrugated sheet represents a durable solution for roofing, cladding, 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.
