Common Issues with Powder Coating
Sharp Edges should be rounded
All painting systems whether it be wet paint or powder coating are more vulnerable on sharp edges because at these points it is usually a thinner coat. On the picture the fabricator has removed the sharp edges on the end of this balcony. A large radius is not required as long as the paint film is uniform thickness, which is not possible on a knife-edge.
This is a popular design for fixing perforated sheet. However, it is a very bad design for avoiding corrosion.
The visible area of perforated sheet will be well protected; however the inner face of the folded edging will start to go rusty in a matter of weeks.
On close observation, it can be seen that it is not painted. This is because there is no practical way of getting the paint in there, leaving it with no protection. To compound the problem, water will fill the bottom edge. Within a year, this may need replacing. If this is an obligatory design, stainless steel should be used with drain holes. Once painted introduce oil, or wax oil, this will help protect the un-painted areas.
