BLD Cold-rolled Steel: Understanding Drawing-grade Selection
Published
BLD is described as a drawing-quality grade in relevant mill literature. This guide covers applications, purchasing considerations and how to discuss the project with Jiangsu Gaozhen. Jiangsu Gaozhen handles enquiries by grade, dimensions and processing requirements.
BLD Product and Material Selection
BLD is described as a drawing-quality grade in relevant mill literature. It should not be relabelled as suitable for arbitrary deep-drawing geometries.
Applications and Manufacturing Scenarios
Formed appliance panels and shallow covers need separate forming and cosmetic specifications. A specialised designation with additional suffixes may carry different requirements.
What to Specify Before Purchasing
Confirm the full designation, standard and surface grade. Specify any painting or lamination route. For complex draws, establish the needed forming capability through engineering assessment and trials rather than a catalogue label.
BLD enquiry: from the part drawing to supply requirements
For BLD enquiries, provide the drawing material requirements or historical certificate alongside the catalogue designation. Describe drawn geometry, visible faces and subsequent piercing. Link an approved sample to gauge, surface and process records. Samples support comparisons under defined conditions; changes to the part or tooling need another forming and assembly assessment.
Gaozhen Catalogue Dimensions and Processing
This Gaozhen catalogue entry lists thickness 0.2-6.0 mm, width 1000/1250/1500 mm. These are catalogue ranges, not a statement that every combination is in stock. Confirm the exact combination of dimensions, condition and other options for the project.
For cold-rolled projects, begin with the developed blank. Discuss cut-to-length sheets for individual blanks or slit coil for continuous stamping. Include bending, piercing and finishing so dimensions, edges and surface requirements are coordinated.

About Jiangsu Gaozhen Trading Co., Ltd.
Jiangsu Gaozhen Trading Co., Ltd. handles product and sourcing enquiries for steel sheet, coil and related metal strip. Customers can identify a grade in the catalogue and discuss drawings, service conditions and processing routes. Requirements for cut-to-length, slitting, laser cutting, CNC shearing or bending can be raised alongside the stock enquiry, with arrangements assessed for the actual material and dimensions.
Gaozhen Product Families
The Gaozhen catalogue covers cold-rolled, hot-rolled, coated and pickled steel; spring steel; carbon-steel strip; stainless sheet and coil; zinc-copper-titanium materials; and titanium-copper alloys. These families address different material requirements. Start with the drawing-specified grade and product form rather than substituting across families on the basis of a similar name.
