The quality of these is very good I used these as mounting rails for solar panels that matched the length so was also able to use combiner bars to add stability to the array. Used lots of hardware for these rails and everything fit great. My use is not normal but doesn’t detract from the quality of the product

I love these extrusions. Very solid and very precise on the dimensions. Used them to build a frame for our fireplace and attached screen for sparks. Now I've started using them to make frames and jigs in the shop.

Everything is fine! The seller is responsible, at first the parcel did not arrive complete, there were not enough connecting corners, then the seller sent them in a separate parcel! The quality of the profiles is very good!

Arrived damaged will be useable to some extent after modifications, additional parts are cheaply cast and some missing or broken or not formed well from casting.

Hardest part is trying to figure out which connectors to use and how many.
