What are the expansion joint requirements for large stainless steel outdoor trash can banks?

Proper expansion joint implementation is critical for large stainless steel outdoor trash can banks to accommodate thermal movement and prevent structural damage. Stainless steel expands and contracts significantly with temperature fluctuations, requiring carefully designed joints at 4-6 meter intervals. Joints should permit movement of at least ±5mm per 10 meters of length, using compressible filler materials compatible with stainless steel to prevent galvanic corrosion. All welded connections must incorporate slip joints or bellows-type expansion mechanisms, particularly at corner sections and mounting points. Vertical joints should include weep holes for drainage prevention while maintaining continuous weather sealing. Installation must follow ANSI/AISC standards for outdoor structural applications, considering local temperature ranges and solar exposure patterns. Regular inspection cycles should verify joint integrity, checking for material fatigue, sealant degradation, and proper movement clearance to ensure long-term durability against environmental stresses.
