Q: What determines the safe spacing of tie rods?

Tie spacing is governed by the maximum lateral pressure of fresh concrete, which depends on pour rate, concrete temperature, slump and wall height, plus the allowable load of the rod, the waler and the panel facing. Spacing must be calculated per pour, not copied from a previous project.

Q: What is the lead time?

Stocked sizes: ready to ship within 3 days. Custom sizes made to drawing: 7-15 days. Lead time is counted from order confirmation and may vary with surface treatment and order volume.

Q: Do you provide samples?

Yes. Standard samples are available for evaluation before bulk order. Sample lead time and courier arrangement depend on the item and destination.

FAQ Teknis

Set Koni Naik — Jawaban untuk Insinyur dan Pembeli

Which steel grade and surface treatment should I choose? +

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.
