DD13 Pickled Coil: Blank Layout and Trimming for Drawn Trays
Published
DD13 is a hot-rolled steel for cold forming, supplied as pickled coil. For equipment trays with rounded side walls, blank size, drawing direction and trimming allowance should follow the formed profile; the cut-to-length coil size is not the final tray size. Jiangsu Gaozhen handles enquiries by grade, dimensions and processing requirements.
DD13: material and applications
In the Gaozhen product catalog, DD13 is grouped under hot-rolled pickled coil for cold-formed parts. Compared with cold-rolled stock, hot-rolled pickled material differs in thickness range and surface condition; buyers should treat pickled coil as forming stock, not as pre-sized tray sheet. Its selection value lies in balancing the drawn profile and later trimming for equipment trays with rounded side walls. The pickled surface provides a basis for pre-paint treatment, but whether degreasing can be omitted depends on incoming protection and the coating process. Thickness variation and bottom flatness should be stated in the inquiry for supplier evaluation.
Tray Part Stock and Processing Arrangement
An equipment tray generally consists of a bottom panel, rounded side walls and trimming allowance. Blank size should be derived from the developed profile of the final tray, with trimming allowance added; the cut-to-length coil size is not the final tray size. Surface oil must be matched to the subsequent coating process: pickled coil may carry protective oil, and whether degreasing is needed before painting depends on incoming protection and the coating line. Thickness variation and bottom flatness should be stated as acceptance items in the inquiry.
Inquiry and Purchasing Points
For an inquiry, provide a sketch of the drawn profile, the developed blank size, permissible thickness variation and bottom flatness requirements, and state the trimming allowance arrangement. This helps the supplier judge whether the pickled coil's thickness range and surface condition suit the tray. The purchasing reason is that thickness and surface condition of hot-rolled pickled stock affect the drawn profile and trimming amount; ordering only by cut-to-length coil size may leave little room for adjustment in forming and trimming. Surface oil and pre-paint treatment should also be included in the inquiry to avoid a mismatch between incoming protection and the coating process. Omitting degreasing cannot be generalized; it depends on incoming protection and the coating process.
Can Pickled Stock Skip Pre-Paint Degreasing?
Pickling removes hot-rolled scale; it is not the same operation as degreasing before painting. Pickled stock may carry protective oil, and handling or fabrication can change cleanliness. Follow the coating system’s preparation requirements and validate cleaning and adhesion on actual incoming or fabricated samples rather than omitting checks because the stock is described as pickled.
DD13 dimensions and supply enquiry
The Gaozhen DD13 product page lists these catalogue dimensions: Thickness range: 0.8-20 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 pickled stock alongside cut-to-length, slitting and drawing-based cutting. Include the later manufacturing route for parts requiring bending or joining.
