Question 1

How is wind load accounted for in transmission tower design?

Accepted Answer

IS 802, or the destination country's equivalent transmission line design code, specifies the wind load methodology based on conductor tension, span length, tower height and terrain category. This is a structural engineering calculation, not something read off a catalogue. If you don't have your own design, confirm whether the fabricator's engineering team can support tower design against your site's wind data.

Question 2

Can existing tower designs be re-galvanized or refurbished rather than replaced?

Accepted Answer

This depends on the members' current condition and whether they can be de-galvanized, inspected and re-galvanized without compromising structural integrity. It needs a site-specific assessment rather than a general answer. For new project scope, new fabrication to current design standards is more straightforward and gives a fresh warranty on the galvanizing.

Question 3

What is match-marking and why does it matter for tower assembly?

Accepted Answer

Match-marking stamps or tags each fabricated member with a unique identifier tied to its exact position on the tower assembly drawing, so site crews install each piece correctly among potentially hundreds of similar-looking angle sections. Poor or missing match-marking is a common cause of assembly delays and errors on large tower projects, so confirm this is standard practice with your supplier.

Question 4

Can tower fabrication be supplied with the bolting and connection hardware included?

Accepted Answer

Yes. Galvanized bolts, nuts and washers matched to the tower's connection design typically come as part of the complete package, so site erection doesn't require sourcing fasteners separately or matching grades independently.

Question 5

What is the galvanizing thickness standard for transmission towers?

Accepted Answer

ASTM A123 minimum 86 µm zinc coating for members 6 mm and thicker; 75 µm for thinner members. Some utilities (PowerGrid, ADWEA) specify higher. 120 µm or class M for coastal corridors. We bath-test every batch with a magnetic thickness gauge and ship the test report.

Question 6

What is the India–UAE CEPA preferential duty benefit, and how does a UAE buyer claim it?

Accepted Answer

The India–UAE Comprehensive Economic Partnership Agreement (CEPA), in force since May 2022, reduces import duty to 0% for qualifying goods originating from India, replacing the standard 5% Most Favoured Nation (MFN) tariff on engineering metal products. Product categories that typically qualify: cable trays (HS 7308), earthing electrodes and fittings (HS 7326 / 7413), copper busbars (HS 7407 / 7413), and structural steel assemblies (HS 7308 / 7314). Rules of origin requirement: goods must be manufactured in India with at least 40% value addition in India, or undergo a qualifying change in tariff heading. To claim the benefit: Vajra obtains a Preferential Certificate of Origin (P-CoO) issued and endorsed by EEPC India or an authorised Chamber of Commerce for UAE CEPA. The buyer presents this P-CoO to UAE Customs at the import declaration stage, without it, the 5% MFN rate applies. On a USD 30,000 cable tray order, CEPA saves approximately USD 1,500 in import duty. Confirm your exact HS codes with your UAE customs broker before finalising the order, as some sub-categories have additional rules of origin requirements.
