FAQs
How much is the galvanizing cost per kilogram, and how is it calculated?
We have a base rate, but pricing is negotiable for bulk orders. The cost is calculated based on the post-galvanizing weight in Baht per kilogram.
What galvanizing standards do you follow?
- American Standards: ASTM A123/A123M, A153/A153M
- British Standards: BS 729
- International Standards: BS EN ISO 1461
- Australian Standards: AS 1214, AS/NZS 4680
- Japanese Standards: JIS H8641
- German Standards: DIN 50976
What is the difference between ground finishing and non-ground finishing?
With ground finishing, we remove excess zinc drips and wire marks. Without it, the surface remains raw and requires customer-side finishing. Opting out of grinding can result in faster lead time.
How long does galvanizing take?
Typically 5–7 working days, depending on workload. Smaller quantities may be completed sooner.
How do I make a payment?
Our accounting team will notify you of the total cost before pickup. Payment can be made in cash on delivery or via bank transfer in advance.
Can you pre-drill holes in the steel?
Yes, but we’ll first need to review your drawings or photos. Our team can also consult with you on-site if needed.
What are the bath sizes at each facility?
Saraburi Branch:
- Building 1: 9.0 m (L) x 1.80 m (W) x 3.0 m (D)
- Building 2: 13.5 m x 1.60 m x 2.50 m
- Building 3 (Spinning): 2.0 m x 1.0 m x 1.0 m
Samut Prakan Branch: 13.5 m x 1.60 m x 2.50 m
Rayong Branch: 13.5 m x 1.60 m x 2.50 m
Why does the product surface turn dull gray after galvanizing?
This typically results from high silicon content in the steel combined with high bath temperatures, especially with thicker sections.
Why are there black spots or uncoated areas?
- Weld joints are incomplete or improperly sealed
- The product was not adequately cleaned before galvanizing
How many plants does Siam Steel Galvanizing operate?
We operate 3 branches:
- Siam Steel Galvanizing (Saraburi)
- Siam Steel Galvanizing (Samut Prakan)
- Rayong Galvanizing (Rayong)
Can the steel warp during galvanizing?
Warping is possible due to the 450°C bath temperature, especially for thin or asymmetrical components.
Do you offer transportation service?
Yes. We provide logistics using 6-wheel side-load trucks, each carrying up to ~5.5 tons per trip. Fees depend on distance, and customers are responsible for loading and unloading.
