What end flare looks like
Changes from 10 ga 16‑inch web with 4‑inch flange to 20 ga 2.5‑inch web with 1.25‑inch flange in under a minute, fully automated.
One sentence, every condition true: the size jump, the gauge jump, the changeover time, and the level of automation. We say it the same way in every catalog because we run it the same way in every plant that has it.
A conventional structural roll forming line changes over by hand. The operator pulls shims, swaps spacers, walks down the line with a tape measure, runs a sample, adjusts, runs another sample, adjusts again. On a good day that takes thirty minutes. On a bad day it takes two hours.
Servo-controlled gauging is the engineering answer to that. Every roll station that has to move is driven by a servo motor. The HMI holds a recipe library, one record per part. The operator picks the next part from the menu and the line walks itself to the new recipe while the operator does paperwork.
The technology is patented in the United States as the closed-loop dual-panel servo gauging architecture that makes that walk reliable. It is standard on the Heavy Gauge Structural and Light Gauge Structural Roll Forming Lines, and it is the single largest uptime gain a customer sees when they move from a legacy mill to a TEKFAB line.

Servo-Controlled Gauging
Recipe to recipe in under a minute. No shimming. No tool change. The line never argues with the operator.
Why operators stop hating changeover.
The patent matters because the dual-panel centerline-justified architecture moves both sides of the line in coordination. A line that only moves one panel forces the operator to re-tram the other side every time. A line that moves both panels around a fixed centerline holds tram across the entire envelope. That is the difference between a changeover that works and a changeover that works once.
The HMI matters because it is the operator's interface. Recipes are stored, edited, locked by user role, and exported to a USB stick if a service technician needs them. Servo position feedback is logged so engineering can verify that the line landed where the recipe said.
Together those choices turn a process the floor used to dread into a recipe selection. The line gets the same setup every time. The operator gets twenty-nine minutes back per changeover. Engineering gets a clean record of what ran when.

Inside the recipe
What the operator does.
What the line does.
The recipe holds web width, flange height, gauge zone, return depth, and any auxiliary settings tied to that part. Pick the recipe. Press start. The line repositions every servo-driven station to the new dimensions and signals ready.
