Massive garage 6x5m slat selection

We can choose between a large woodgrain rib or a large panel (L-rib) for our garage door/sectional door (5.25 m x 2.25 m).

The surcharge for the larger rib would be €450.

Apart from the appearance, is there any difference depending on which rib is used, or is the extra cost worth it?

As far as I know (I remember), the number of slats is always the same. So primarily aesthetics. What might be more important is the "filling" (insulation).

Woodgrain looks shabby. Try searching for microprofiled…

There are many pictures of it on the internet, I think the L-groove is the nicest. However, I have to say, based on the pictures, I would have bought Woodgrain because it is cheaper, but in person it actually doesn't look nice (however, it is more resistant to scratches).

We can choose between a large groove woodgrain or a large slat (L-groove) for our garage door/sectional door (5.25 m x 2.25 m).

I couldn't choose anything there because I don't understand it: it is not very helpful when the providers themselves do not understand the terminology. A "groove" refers to the trench / valley in a sheet metal profile, and the term "slat" really only makes sense if the element "section" is double-walled (usually a sandwich sheet-metal-foam-metal), so it makes no sense for a single-walled element. I personally would not call the stile at the junction of two sections a groove. So whether the "grooves" here mean S, M, or L, that is, visually dividing a section in height by grooving it twice, once, or not at all, is not understandable to me from the descriptions. I would prefer—notably for single-walled sections—not to divide the individual sections by grooves. For those who find this too coarse, there is the alternative of the roller door. I find a jalousie look on the sectional door nonsense.

For me personally, this depends on the style of the house or the rest of the appearance. For a straightforward modern house, I would definitely not choose woodgrain, but rather a smooth surface texture and preferably L-groove. For a country house style, I find woodgrain suitable and would choose the M-groove there.

Thank you, we decided against woodgrain and for a smooth/modern L-groove. It fits better with the style of the house and our desired color is available.
