Import Breakaway Square Sign Post — Buy in wholesale FOB from Supplier in China

Better Products Co. manufactures breakaway square sign posts from ASTM A570 Grade 50 structural steel, a hot-rolled carbon steel specification with yield strength of 60,000 psi (410 MPa) and maximum tensile strength of 79,000 psi (540 MPa). The posts are available in square cross-sections of 1 1/2 inch, 1 3/4 inch, 2 inch, 2 1/4 inch, and 2 1/2 inch, with wall thicknesses in 12 and 14 gauge. A zinc primer base and hot-dip galvanised finish to ASTM A653 G90 provide corrosion protection, while powder coating in multiple colours is offered as an alternative finish. Holes of 7/16 inch diameter are punched 1 inch on centre on all four faces, facilitating sign attachment at variable heights.

ASTM A570 Grade 50 is a structural quality hot-rolled steel with improved formability and weldability compared to higher carbon grades. The G90 galvanising designation specifies 0.90 ounces of zinc per square foot of surface area (total both sides), equivalent to approximately 85 micrometres per side, a standard coating weight for outdoor structural applications in moderate corrosion environments. The breakaway function is achieved through engineered weakening at the base coupling, designed to yield upon vehicle impact and reduce crash severity. Typical base details include a slip-base or transformer coupling with frangible bolts, though the supplier description does not specify the exact breakaway mechanism employed.

These sign posts serve highway authorities, municipal road departments, and private development projects requiring MASH or EN 12767 compliant roadside hardware. The multiple size and finish options accommodate varying sign dimensions and aesthetic requirements. Buyers should confirm with Better Products Co. whether the product has undergone full-scale vehicle impact testing to NCHRP 350 or MASH criteria, as compliance documentation is essential for public authority procurement. The 12 and 14 gauge options trade structural rigidity against weight and material cost, with thicker walls preferred in high-wind regions or for larger sign panels.

Better Products Co. operates from No. 59 Gongyenan Road, Jinan, Shandong 250101, China, placing its manufacturing base in a major northern Chinese industrial centre with established steel processing and galvanising infrastructure. The supplier holds harbour trust tier classification with a 0.00% platform response rate and zero recorded average response hours, indicating minimal reliance on or engagement through digital enquiry channels. This pattern is common among legacy manufacturers with established distribution networks or trade fair-based customer acquisition.

The company profile does not disclose founding year, employee count, factory floor area, annual turnover, export markets served, or quality system certification such as ISO 9001. No client references, project portfolios, or production capacity figures are stated. The listing concentrates on a single product family, breakaway square sign posts, without indication of broader roadside safety product lines. Buyers should conduct independent verification of Better Products Co.'s operational scale and quality management maturity through direct factory audit, third-party supplier verification services, or chamber of commerce reference checks in Jinan before committing to substantial orders.
