FG503463 is an archived LOPO grooved terracotta facade panel reference in a red fired-clay tone. Its deep, repeated ribs create pronounced shadow lines, giving the surface more directional character than a flat panel. The groove width, depth, spacing and panel orientation can all be adjusted in principle, but current manufacturing limits and the complete facade assembly must be confirmed for each project.
How grooves change the facade
A grooved face is not merely decorative. In oblique daylight, each rib casts a small shadow, so the elevation changes as the sun moves. Closely spaced grooves create a finer texture, while deeper or wider profiles read from farther away. Horizontal ribs can stretch a facade visually; vertical ribs can reinforce height and make rain streaking or panel alignment more noticeable.
The rhythm should be coordinated with joints, openings and corners. If the groove spacing stops awkwardly at a cut edge, the interruption may be more visible than on a flat panel. Full-size samples help the architect judge shadow, colour and scale together before committing to an elevation-wide pattern.
Archived FG503463 product reference
The original page contains two different dimensional descriptions: its excerpt lists 500 × 1200 × 33 mm, while the body table lists 500 × 600 × 34 mm. Both records are preserved here so the conflict is visible; neither should be used for procurement without a current drawing and confirmation.

Standard ranges and customization in the old listing
The archive described a broad design range. These values are useful for early discussion, but tooling, firing behaviour, structural checks and order volume determine what can be produced now.

Translate the surface idea into buildable details
Groove geometry
Define the number, spacing, width and depth of grooves, plus the flat margins at panel edges. These details affect visual continuity and may influence cleaning.
Panel module
Set out real elevations to reduce narrow cuts. Coordinate the rib direction with window heads, sills, parapets, corners and soffits.
Colour range
Approve representative fired-clay samples and decide how normal tonal variation should be distributed across deliveries and the installed wall.
Support system
Review the hollow section, edge profile, clips, rails, brackets, cavity, insulation and membranes as one facade assembly, not separate products.
The legacy page described the panel with broad benefit claims such as waterproof, anti-noise, fireproof, frost-resistant, self-cleaning and non-fading. These should be translated into measurable project requirements. Ask for current reports relevant to water absorption, freeze–thaw exposure, reaction to fire, structural capacity and the specified fixing system.

Project review and sample sequence
- Share the building location, elevations, wind-design information and target module.
- Confirm the current panel section, groove geometry, finish and fixing approach.
- Review representative samples under relevant light, then prepare a larger mock-up.
- Coordinate joints, corners, openings, replacement access and cleaning with the facade consultant.
- Approve current test documents and production information before release.
