Objective Aiming at traditional wooden brackets′ various defects including poor adaptability, insufficient strength and short lifespan in packaging and transportation of steel coils, and a certain enterprise′ s needs an adjustable, a removable, recoverable new structure was designed for vertical roll cross-shaped steel bracket. Methods This structure was mainly composed of cross connectors and four retractable bracket arms. The bracket arms could stretch out and draw back freely, and the bracket could adjust its size. Results When analyzing the bending strength and rigidity, the maximal stress and maximal deformation of the bracket were 50.23 MPa and 0.54 mm, respectively. The corresponding finite element results were 50 MPa and 0.64 mm, respectively. Conclusion The finite element simulation results and theoretical calculation results were basically consistent， so the design of the new cross bracket structure was reasonable.
