However, how to get the cheapest rolling shutter doors from China without compromising on quality? Here below are 7 tips for your reference when buying from China. ► Tip 1, Make sure the thickness of steel slats is enough according to the PI/contract that you have signed. Some suppliers might quote you a very low price to get the orders first, and then they will use less thickness of steel slats to reduce their cost and increase their margin. ► Tip 2, Check the end clips on both sides. The end clips fixed on both sides are crucial because they will prevent the curtain from lateral movement. If it's poor quality end caps, then the slats might slide out of the curtain and the door will be stuck, if the motor keeps running, the curtain will be damaged or broken, which might cause safety issues. ► Tip 3, Check the bottom rail. Make sure the bottom rail is heavy enough to its gravity stress to lead the curtain to run more smoothly, especially for manual operation steel roller shutter doors, we could put some iron bars inside the bottom rail or sand inside the bottom rail if necessary. ► Tip 4, Check the guide rail/track. The guide rails fixed on both sides are used for the smooth operation of the curtain and offer security. If the guide rail is weak, then it will be earlier to break in. ► Tip 5, Check the shaft/barrel. The shaft used for hanging the curtain on the top of the roller shutter door is critical, the curtain might fall down if the shaft is not strong enough, which might cause safety problems. ► Tip 6, Check the quality of powder coating. Some of you might need different colors for the steel rolling shutter doors, remember to check the quality of the powder coating, otherwise, it will be easier to peel off and discolor. ► Tip 7, Check the roller shutter motor. The roller shutter motor is the most important thing for an automatic steel rolling shutter door, if the motor doesn't work, then the door doesn't work either, so choosing a good brand of motor always means a lot. In a word, choosing a professional manufacturer of steel rolling shutter doors means a lot to you.
