The TerraGroove 300 is a roll-formed V-groove steel siding profile with narrow linear faces and defined V-shaped recesses. Two face-width options create a controlled rhythm for horizontal or vertical wall and soffit applications.
Confirm the profile and finish with samples, then send quantities and project requirements for a written quotation.

All dimensions are nominal. Finished lengths are confirmed for the actual order, handling plan, and transport method.
Overall formed width is not effective installed coverage. Joint and overlap details must be confirmed before using this dimension for quantity calculations.
These are common gauge selections, not the full extent of our material supply. Other gauges and metal thicknesses can be requested; suitability for the selected profile is reviewed before production. The Core reference gauge for this profile is 26ga. Material, coating system, decimal BMT, quantity and production details are confirmed in the written quotation.

Printed grain and solid colour use the same formed profile. Compare a darker wood-look, a lighter wood-look and Ice White as the three panels meet.
The wood appearance is a printed coating, not timber. Confirm the selected finish and material in the project quotation.

How the edges meet
The fixing flange belongs to one edge. The adjoining panel's return enters the receiving fold and conceals that fixing edge.
The animation explains the connection. It does not specify fastener type, spacing or installation tolerances.
TerraGroove 300


This land is the fixing edge. It will sit behind the adjoining panel face.

The adjoining return slides into the folded receiving edge.

The return is engaged inside the fold, leaving the narrow V-groove between the faces.
Connection illustration. Follow the project-specific installation details.
Plan the elevation
Vertical lines lead the eye up an elevation. Horizontal courses emphasize its width. Openings, corners and terminations need coordinated trim details in either direction.
Profile, connection and direction


The face, fixing flange and receiving fold form one continuous steel section.
The adjoining return enters the receiving fold. The fixing flange sits behind the next panel face.
Adjacent panels repeat at the selected face width, retaining the same formed V-groove.
Compare horizontal and vertical lines. Coordinate openings, terminations and trim with the project layout.
Solid colour and printed grain change the appearance, while the formed profile stays the same.
