Selection tips

  • Match shaft length to child height: 55-65 cm is the common range, and an over-long shaft drags on the ground.
  • A fibreglass shaft does not conduct electricity, which is the safer choice for outdoor use by children, at a cost.
  • Plug or round the tube ends: an open tube cuts fingers and lets water in to rust the inside.
  • Coatings must resist saliva and sweat migration (EN 71-3), not just salt spray.

Manufacturing process & quality control points

Qinxi in-houseSupply chain / partnersIn-house or supply chain
  1. 1

    Tube cutting and end forming

    Supply chain / partners

    The shaft is cut to the shorter kids length and the ends are formed. Kids frames are scaled down, not just shortened, so wall thickness is chosen for a smaller hand rather than for minimum weight.

    Quality control points

    • Cut length and squareness · Caliper + squareness gauge per drawing · First article + 1 pc per 2 h
  2. 2

    Hole punching and deburring

    Supply chain / partners

    Latch, runner and rivet holes are punched and every edge is deburred. On a kids frame there is no acceptable burr anywhere: a sharp edge is an automatic safety fail.

    Quality control points

    • Burr and sharp edge · Gloved touch check plus 10x loupe · 100%
  3. 3

    Surface finishing

    Supply chain / partners

    Plating or powder coating is applied by the supply chain and checked against EN 71-3 migration limits for the elements it contains, not just for appearance.

    Quality control points

    • Coating thickness · Thickness gauge per buyer spec · Per batch
    • Coating adhesion · Cross-cut and tape test (ISO 2409) · Per batch
  4. 4

    Straightness and fit check

    Supply chain / partners

    Shafts are checked straight and dry-fitted with the runner before assembly.

    Quality control points

    • Straightness and runner fit · Roll on flat plate; manual slide over full stroke · 100%
