Nice work
.......
Are you looking for some sliders?
Regards "curvature of rectangular profile" the person who manufactured my rock sliders said to me that he uses a very very large press to bend the rectangular profile.
Metal is very thick so it was a massive machine I think!!
Tomorrow will see what friends say about bending.
Your square profile what size is a?
Sorry, what do you mean "your square profile what size is a?"
Peter,
Normal size is around 50mm wide by 75mm deep but different companies use different sizes.

Think can change the color.
