Section Dimensional Specification Checklist
| # | Dimension Item | Engineering Review Significance | Specified Value (mm / deg) |
|---|---|---|---|
| 01 | Feeding Strip Width | Total flat developed coil width prior to roll forming. Determines slitting width and tooling stations. | |
| 02 | Effective Coverage Width | Net installed building coverage after side-lap overlap. Must match architectural requirements. | |
| 03 | Rib Height (Profile Depth) | Vertical height from pan valley to top rib crest. Dictates required shaft diameter and station count. | |
| 04 | Rib Pitch & Spacing | Center-to-center distance between adjacent major profile crests. | |
| 05 | Crest & Valley Widths | Flat horizontal span of top crest and bottom pan. Note if fluting/stiffener ribs are needed. | |
| 06 | Overlap & Siphon Detail | Geometry of under-lap and over-lap ribs. Note if capillary break groove is required. | |
| 07 | Inside Bend Radii | Corner radius on bend passes. Prevents coating micro-cracking and material fracture. |
02
Raw Material Properties & Coating
| # | Material Property | Engineering Review Significance | Project Material Input |
|---|---|---|---|
| 01 | Metal Substrate Type | Specify substrate: Carbon steel (commercial/structural), Aluminum, Stainless, or Copper. | |
| 02 | Decimal Thickness Range | State confirmed decimal range in mm. Specify if Base Metal (BMT) or Total Coated Thickness (TCT). | |
| 03 | Yield Strength & Grade | Tensile and yield strength range from mill certificate. Required to calculate springback compensation. | |
| 04 | Coating System | Specify protective coating: Galvanized (GI), Galvalume (GL/Aluzinc), Prepainted (PPGI/PPGL), or ZAM. | |
| 05 | Protective Film Lamination | Is automated clear PE protective film application required before roll forming entry? |
03
Secondary Features & Tolerance Framework
| # | Secondary Operation | Engineering Review Significance | Customer Specification |
|---|---|---|---|
| 01 | Hole / Slot Punching | In-line hydraulic punching for bolt holes, web slots, service knockouts, or drainage holes. | |
| 02 | Hole Spacing & Pitch | Centerline spacing between hole groups along the length of the product. | |
| 03 | Dimensional Tolerances | Specify required tolerances in written technical schedules per project contract. |
