• This DZ97189603230 step ladder frame is a dedicated right side cab access support component for Shaanxi heavy duty trucks
• The whole frame is formed by integrated welding of thick steel pipes and stamped steel plates with uniform galvanized anti corrosion surface treatment
• Multiple reserved mounting holes on brackets and cross beam support flexible installation matching original truck chassis fixed positions
• Reinforced full weld connections at all pipe and plate joints improve overall structural bearing capacity for daily climbing load
• All frame outer dimensions hole spacing and bracket bending angles strictly comply with original vehicle OEM mold manufacturing standards

• Full galvanized metal surface effectively resists rain mud and road salt erosion to prevent rust during long term outdoor vehicle operation
• Thick wall steel pipe main frame delivers strong load bearing performance to bear repeated climbing weight without permanent bending deformation
• Multi hole cross beam design allows flexible adjustment of step installation height to fit different maintenance and entry demands
• Fully sealed welding joints eliminate stress concentration points and avoid weld cracking under continuous bumpy road vibration
• Curved reinforced bottom brackets distribute bearing force evenly to reduce impact damage to chassis mounting points

• Every finished ladder frame completes static load bearing test to verify stable structure under maximum rated climbing weight pressure
• Full weld joint inspection checks all welding seams to eliminate incomplete welding and hidden crack defects inside the assembly
• Salt spray anti corrosion aging test confirms long term rust prevention performance under harsh rainy and muddy driving environments
• All thick steel pipe and stamped plate raw materials meet heavy commercial vehicle metal bracket structural strength standards
• Each step ladder welding assembly carries exclusive part number marking to realize complete traceability of production and inspection records
