DX56D+Z Galvanized Steel for Deep Housings: Drawing and Coating Checks
Published
DX56D+Z galvanized sheet and coil can be assessed for deep housings. Initial drawing, redrawing and trimming each need checks, including wall thinning, corners and coating condition on actual samples. Jiangsu Gaozhen handles enquiries by grade, dimensions and processing requirements.
DX56D+Z: material and applications
DX56D+Z is a hot-dip galvanized sheet and coil grade for demanding forming applications; +Z identifies the zinc coating. A deep housing needs formed walls, an installation opening and bottom radii, so forming behaviour and coating condition must be considered together. Flat incoming sheets may look alike, while thinning and surface changes after drawing require sample inspection.
Show wall depth, bottom geometry and assembly-opening dimensions on the part drawing. If welding or painting follows, identify joining areas and visible faces before selecting the surface requirements.

Processing Focus Across Three Stages for Deep Enclosures
Deep-drawn enclosures typically go through first draw, redraw, and trimming. The first draw focuses on whether the sheet flows evenly at the die radius; check blank holder force settings and lubrication, and record thickness change locations after drawing, especially at the bottom radius and sidewall transition. In redraw, assess whether wall thinning from the previous stage affects subsequent forming; measurement points should correspond to first-draw records for comparison. Trimming mainly controls contour dimensions and burrs, while observing coating condition near cut edges. Process records should include die number, lubrication method, thickness measurement locations, and operator team so trial information can be traced.
Linking Samples and Bulk in the Order
After sample approval, turn the grade, coating designation, gauge and surface condition into production purchasing requirements linked to the approved process revision. Retain updated records where blanks, tooling or lubrication changed during trials, rather than carrying initial settings into production.
Agree incoming checks such as dimensions, surface condition and batch identification. Samples from intermediate drawing stages can help show where a later deviation first arose. Linking material records, process records and part measurements is more useful for investigation than keeping only a final acceptance report.
Can Incoming Inspection Be Skipped After a Successful Trial?
No. A successful trial only shows the sample can be formed under specific die and process conditions; the sample and bulk batch must be comparable. Incoming inspection should still verify grade, coating identification, dimensions, and surface condition, with batch records retained. Skipping inspection may allow material differences between sample and bulk to go unnoticed. Inspection items can follow the order agreement and need not be excessive.
DX56D+Z dimensions and supply enquiry
The Gaozhen DX56D+Z product page lists these catalogue dimensions: Thickness range: 0.25-3.0 mm; Width range: 1000/1250/1500 mm. These values support specification discussions; confirm the required combination of gauge, width and condition for the material.
Discuss substrate, coating, surface condition and blank dimensions separately, then coordinate stock with cut-to-length, slitting or forming needs.
