What is the minimum pitch for a steel roof?
1/4:12

What is a pitch break?
Pitch breaks typically occur at higher volumes when a swelling firmly touches the other side and splits the membranous vocal cord’s vibrating length abruptly into two separate segments. The mechanical phenomenon underlying a pitch break is nearly identical to an onset dealy from a swelling.
What is the minimum pitch for a metal roof?
The minimum slope for a metal roof with exposed fasteners and seams without sealant is 3:12, which means 3” of drop for every 12” of horizontal run. Roofing with exposed fasteners and lapped seams with sealant can go lower – ½:12.
What underlayment should be used under metal roofing?
felt underlayment
The traditional and most common material used for roof underlayment on a steep-slope metal roof is non-perforated, asphalt-impregnated felt underlayment. There are several types of felt underlayment including both organic reinforced and inorganic reinforced.
Do you need drip edge on metal roof?

What is the size of the punch and die for bending?
In order to bend workpiece in different length, the punch and die are separated into below size: 10+15+20+40+50+100+100+200+300=835 What are press brake dies made of? Generally, the materials of press brake die including T8 steel, T10 steel, 42CrMo, and Cr12MoV.
What is the standard size of press brake dies?
Generally, the standard length of the press brake punch and die set is 835mm. In order to bend workpiece in different length, the punch and die are separated into below size: 10+15+20+40+50+100+100+200+300=835 What are press brake dies made of? Generally, the materials of press brake die including T8 steel, T10 steel, 42CrMo, and Cr12MoV.
How to choose the press brake Punch and dies?
In order to extend the service life of mold, the press brake punch and dies are designed with rounded corners as far as possible. Commonly used brake press dies are as follows. Generally, the height of flanged edge L≥3t (t=plate thickness). If the height of the flanged edge is too small, even use bending die is not conducive to forming. 1.
