What data is needed for a coil processing line quote?

1. Material and coil data

Start with the steel grade or alloy type, yield strength, tensile strength if available, surface condition and incoming coil dimensions. For coil processing equipment, the width range, thickness range, inner diameter, outer diameter and maximum coil weight decide the mechanical strength of the entry section.

• Material grade and surface requirement.
• Thickness range and width range.
• Coil inner diameter, outer diameter and maximum coil weight.
• Incoming coil condition, including camber, surface sensitivity and edge quality if known.

2. Finished product requirements

The equipment layout changes depending on whether the project needs sheets, narrow strips, recoiled finished coils or flatness improvement. Share finished width, finished length, tolerance target, stacking method or recoiling requirement.

For reference, existing Junjian cut-to-length and slitting line ranges include material thickness references from 0.2-2.0 mm, project ranges up to 16 mm, entry width references from 600-1250 mm and project ranges up to 2000 mm. Final configuration still depends on the confirmed material and production target.

3. Process route and speed target

A cut-to-length line may include coil loading, uncoiling, leveling, measuring, shearing, conveying and stacking. A slitting line may include uncoiling, looping, side guiding, slitting, edge scrap handling, tensioning and recoiling. Tell the engineering team which route is required and whether continuous high-speed production is the priority.

• Target process: cut-to-length, slitting, rolling, leveling, recoiling or support module.
• Expected process speed and daily shift schedule.
• Required automation level and operator arrangement.
• Any upstream or downstream equipment that must be connected.

4. Workshop and utility information

Workshop conditions affect the line layout. Provide available floor length and width, crane capacity, material flow direction, power supply and any foundation limits. A simple layout drawing can reduce repeated quotation revisions.

5. Commercial and service requirements

For international projects, also confirm destination country, expected delivery schedule, documentation needs, installation support and commissioning requirements. These details help define the service scope without overstating equipment specifications.
