Core Criteria for Heavy Equipment

Choosing strength equipment depends on material density. GG20 gray cast iron offers consistent compactness. Carbon 45 steel maintains lasting straightness under load.

Manufacturing Standards

A quality piece hides nothing. The absence of thick paint lets you verify the integrity of the casting. The metal breathes and retains its natural grain.

• Inner diameter precision: Clean fifty-millimeter bore to minimize sleeve play.
• Strict weight tolerance: Deviation kept within a few grams of the stamped nominal weight.
• Zero porosity: Sound surface resulting from fine sand casting.

Common Mistakes

Thick plastic coatings often conceal porous iron or concrete filler. These weights crack on the slightest rough impact. Loosely fitted metal inserts end up shifting after a few months of work.

Selection Recommendations

Opt for bare plates treated with protective vegetable oil. Choose carbon 45 steel sleeves to prevent permanent bending during heavy pulls from the floor.
