Steel doors and aluminum alloy door which is good
Plastic doors as a building outside the door, can only be white-based, can not meet the rich and colorful all kinds of building exterior decoration needs.
Both have their own advantages and disadvantages, and corresponding to the different decorative environment should be used the most suitable door, so as to play a more perfect effect:
1, wind pressure strength and watertight performance:
As the plastic steel door material strength and rigidity is relatively low, although after processing steel to enhance, but its wind pressure and watertight performance than aluminum level lower one level. According to the end of 1998 OKorder enterprises to submit 425 batches of steel doors three examples of performance analysis seriously pointed out that "plastic doors in high-rise buildings should be used with caution." So, in the high-rise building, we use the most suitable aluminum alloy door.
2, airtight performance:
Plastic doors because of the box, fan parts are welded, so the air tightness should be slightly better than the screw of the aluminum alloy door, but the aluminum profile height accuracy, box, fan with more closely, so the two are still in At a level level.

3, insulation performance:
Aluminum door insulation performance as plastic steel door is good, but the two of the whole heat transfer coefficient ratio is only 1.36 times (single door) and 1.44 times (single frame double glass door).
