1. Why Complete Information Gives Better Quotes
Steel quotations are drawing-driven calculations; the completeness of your input decides whether the quote is executable. Incomplete information forces suppliers to assume, leading to extras or schedule drift later. Preparing the checklist below once allows multiple suppliers to quote on the same basis.
2. Drawings and Member Lists
- Structural design or detailing drawings: member sizes, sections, connections and notes;
- Bill of materials (BOM): quantities, unit sizes and weights;
- Grade and location notes, ideally marked on the drawings.
3. Grades and Standards
- Material grades: Q235B, Q355B, Q355C, etc. (keep grades in the original, do not translate);
- Applicable standards: national, American or European standards per project;
- Surface finish: black, shot blasting, painting or galvanizing requirements.
4. Fabrication and Delivery Parameters
- Fabrication scope: whether cutting, drilling, welding and straightening are needed;
- Lead time: target delivery date and partial delivery requirements;
- Destination and packaging: port or address, break-bulk, flat rack or container, packing and sea freight requirements.
5. Quality and Inspection Requirements
- Quality documents: material certificates, dimensional inspection records, NDT reports, etc.;
- Third-party inspection: whether outside witnessing or acceptance is required;
- Acceptance standard: which code governs inspection and who confirms it.
The more complete your information, the closer the quote and lead time are to reality.
