DOLADISPLAY's plastic step riser products represent the pinnacle of polymer engineering for retail display applications. These high-performance units utilize advanced co-polymer blends that deliver the structural integrity of metal with the lightweight advantages of plastics. The material formulation combines impact-modified polypropylene with glass fiber reinforcement, achieving exceptional rigidity (18,000 psi flexural modulus) while maintaining UL94 V-0 flame retardancy. Precision rotational molding creates uniform wall thickness (4-6mm) with consistent load distribution across all stress points. The UV-stabilized compounds prevent yellowing or brittleness under continuous fluorescent exposure. Specialized versions include static-dissipative grades for electronics displays (10^6-10^9 ohms/sq) and conductive formulations for ESD-sensitive environments. The interlocking design features over 200% more connection points than industry standard, ensuring wobble-free performance even when fully loaded. All products exceed ANSI/BIFMA testing protocols for commercial use.
