Production and packaging process
Steps: The melting-casing- MAO embryo-Polishing-Galvanized-Threading-Detection-Packaging
Blast-furnace smelting +electric furnace adjustment duplex smelting technology,
72 hours-3 sections-electric annealing technology, comprehensively
ensure our products’ quality to be the best.
Take”six check +two inspect+one examine” measures,
using Germany made FOUNDRY-MASTER Xline to check each pack of liquid iron’s chemical composition, ensure low defect rate and stable product quality.
Carefully choose multiple vendors, using Shanghai-made 99.99 high purity zinc,
remove all the impurities which is bad product quality control,
brighter surface, more fine zinc coat, better protective properties.
Small packaging numbers, which is easier for handle; carefully choose
high quality non-recycled plastic made double-woven bag,
make the product to be more break-resistant,
no need worry about broken bag during handing process.
