Üretim Süreci

**Cutting & forming**Bar cutting, cold heading and plate forming to drawing dimensions.

**CNC thread rolling**Rolled threads for fatigue strength and consistent pitch diameter.

**Heat treatment**Quenching and tempering for class 8.8 and above, with process records.

**Surface treatment**Black oxide, zinc plating or hot-dip galvanizing to the specified thickness.

**Gauge & batch test**Thread gauging, hardness and tensile checks with batch test reports.

**Packing & marking**Set or BOM packing, VCI protection and seaworthy crates.

Malzeme Sınıfları Açıklaması

Sınıf	Notlar
Q235	Plain carbon steel. Economic option for light and medium formwork loads. Not heat treated.
45#	Medium carbon steel. The standard formwork tie rod grade in China; quenchable to class 8.8.
40Cr	Alloy steel. Higher hardenability and better fatigue performance than 45#; used where repeated reuse matters.
Class 10.9 bolt	Quenched and tempered alloy steel bolt used in the climbing cone set. Not electroplated without a documented baking cycle.
QT450-10	Ductile (nodular) iron with 450 MPa tensile and 10% elongation. Used for sleeves and embedded plates where toughness and castability matter.
HRB400	Hot-rolled ribbed bar (threaded steel) to Chinese standard. Used for embedded foot bolts; good bond with concrete.
