I ordered a fence and the provider agreed to deliver it made from hot dip galvanized steel covered with powder painted finishing. The price was significantly bigger thank with the electro galvanization.
They started assembling the whole thing and I have spotted some worrying rust-like stains underneath the construction, on the insides of the C-shape profiles. Please see the pictures.
Am I being scammed? Can you tell, by mere pictures, if it's a hot dip or electro galvanized surface?
Please help. It cost a lot but I am afraid the provider is not honest with me.
Also, on the other part of the element used a brush (don't know a type, toiled cleaning type I guess) and here are the effects before and after.
Some of the dark-red dust is gone but yellowish stains remained. Look similar to what I spotted on some scraps from profiles with some holes in them (also, supposedly hot dip coated and powder painted).
Also spotted some similar constructions in my town and they had technical holes in them (to prevent air bubbles and ex-/imploding of the element while hot dipping) and mine does not have them even almost identical to what I saw. Even more suspicious now...
