When purchasing steel material boxes in bulk, first confirm whether the supplier is a source manufacturer. A source factory can customize size, load capacity, structure and surface treatment to your needs and quote more competitively; middlemen usually only sell standard products and cannot produce drawings tailored to your material dimensions. It is recommended to request factory photos, sample pieces or a sample spec sheet to avoid buying boxes with poor welding or overstated load ratings.
Before ordering, write these items into the contract: box size and dimensions, material and plate thickness, per-box load and stacking layers, surface treatment, quantity and unit price, delivery period, packaging and shipping method, quality standards and after-sales terms. Steel material boxes are non-standard custom products, so always confirm by sample first, then move to bulk production.
