How to Choose A Galvanized Pipe Supplier?

There are many steel pipe manufacturers all over the world. But how to find a reliable one? As an experienced galvanized pipe manufacturer, here are some tips from Wanzhi Steel. Keep reading to find out what you should pay attention to when choosing a galvanized pipe supplier.

1. Quality

Quality is the only way to ensure the safety of your project. Before purchasing, you should confirm whether the supplier has established a stable and effective quality assurance system. Besides, you can check the related certificates. Also, you can ask for samples or check the factory on-site. We will suggest you choose a galvanized pipe supplier with a high reputation.

2. Location

You can find GI pipe suppliers at home and abroad. Some may prefer local suppliers, while some want to buy from suppliers in China or India because of the low price. Here are our tips. If your order is within 5 tons, you’d better choose a local supplier to save your shipping costs. While if you need a large order volume, it will be more cost-effective to choose a Chinese manufacturer.

3. Price

Price is one of the main concerns of customers. You can compare the price from different suppliers, but please do not rely on the price only to avoid being swindled.
