Acceptable SGCC Quality, Delivery Delay on Custom Width Resolved
Ordered 28 tons of SGCC coil, 0.8mm thickness, 750mm slit width, Z120 coating for wall cladding panel fabrication in Bogotá. Material quality itself was acceptable — chemical composition and mechanical properties per JIS G3302 were confirmed on the mill cert. The issue was delivery: quoted 20-25 days for the custom slit width but actual loading happened on day 33, causing a 10-day delay in our project schedule. After raising the concern, the supplier expedited the shipping arrangement and provided partial freight compensation. Communication during the delay could have been more proactive. Quality of the steel is good enough that we would consider reordering, but only after confirming production slot availability upfront before placing the next order.
