Material Grades Explained

GradeNotes
Q235Plain 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.
40CrAlloy steel. Higher hardenability and better fatigue performance than 45#; used where repeated reuse matters.
Class 10.9 boltQuenched and tempered alloy steel bolt used in the climbing cone set. Not electroplated without a documented baking cycle.
QT450-10Ductile (nodular) iron with 450 MPa tensile and 10% elongation. Used for sleeves and embedded plates where toughness and castability matter.
HRB400Hot-rolled ribbed bar (threaded steel) to Chinese standard. Used for embedded foot bolts; good bond with concrete.

Technical FAQ

Formwork Coupler — Answers for Engineers and Buyers

Formwork tie rods are commonly produced from medium and high carbon steel in 8.8 and 10.9 property classes. For corrosion protection: hot-dip galvanizing gives the thickest coating and suits outdoor and marine exposure; Dacromet (zinc-flake) coating avoids hydrogen embrittlement and is preferred for high-strength grades; electro-galvanized is an economical option for general use; black oiled bar is used indoors or where the rod is recovered and reused quickly.
