Materials
Door Frame Materials: Commonly seen materials include aluminum alloy, broken bridge aluminum, and wood. Aluminum alloy is sturdy, durable, not easy to rust, lightweight, and relatively moderately priced. Broken bridge aluminum, based on aluminum alloy, adds heat insulation strips, which gives it better heat insulation and sound insulation performance, making it suitable for environments with high requirements for thermal insulation and noise reduction. Wood, on the other hand, has a natural texture and feel, and can create a warm and elegant atmosphere. However, it requires careful maintenance to prevent moisture-induced deformation. In urban areas, choose doors and windows with good sound insulation properties because there are many vehicles. So, it is necessary to achieve sound insulation as much as possible to provide a quiet environment for employees at work.
Door Leaf Materials: Glass door leaves have good light transmittance, making the space look transparent and open. They are often used in positions such as balconies and partitions and are easy to clean. If privacy is emphasized, frosted glass, colored glass, or artistic glass with patterns can be selected. Metal door leaves, such as stainless steel and aluminum alloy, are sturdy, durable, fireproof, and moisture-proof, and are suitable for areas prone to dampness or fumes, such as kitchens and bathrooms. In addition, some door leaves are made of materials like PVC and fiberboard, which are more affordable and have a certain degree of decorative properties, but may be slightly inferior in terms of strength and durability. The materials of the door leaves should be of high quality because only good-quality materials can produce good products. Choose door leaf materials with good light transmittance, because good light transmittance can lead to good energy conservation. If the light transmittance is not good, lights need to be turned on, consuming electricity, which is also a large economic expense.
Hardware Accessories
Hinges: High-quality hinges should be made of high-strength metal materials, such as stainless steel or copper alloy, and have good toughness and wear resistance. When checking the hinges, observe whether the surface is smooth, without burrs, cracks, and other defects. When opening and closing the door, the hinges should rotate flexibly, without jamming or abnormal noise, and be able to bear the weight of the door to keep the door stable. Hinges are very detailed parts and should be carefully selected. Some parts are very hidden, and if cheap hinges are used, it is very likely to cause problems. Therefore, try to choose high-quality hinges, which can extend the service life. The service life is also a point that customers care about because of various different materials and production times. So, customers attach great importance to the quality of this product. Good quality leads to high product sales, and consumers will repurchase, which is also a way to increase customers indirectly.
Pulleys: The quality of the pulleys directly affects the smooth sliding and service life of the folding door. Good pulleys usually use wear-resistant materials such as nylon and POM, and the wheel axles are made of stainless steel or copper materials, which rotate flexibly and produce little noise. Gently push the door by hand to feel whether the pulleys slide smoothly, without jumping or blocking phenomena. Pulleys are the key part of doors and windows. As long as the door is opened and closed in daily use, the pulleys will be used. Also, some relevant lubricating oil should be used for the pulleys. For example, maintaining the pulleys with lubricating oil can effectively extend their service life.
Door Locks: Choose suitable door locks according to the usage scenarios and safety requirements of the folding door. For folding doors used at home, door locks with a simple appearance and easy operation can be selected. For commercial places or areas with high security requirements, door locks with good anti-theft performance, sturdiness, and durability are needed. At the same time, check whether the door lock is firmly installed and whether the key can be inserted and pulled out smoothly. When choosing door locks, also select those of better quality. Good door locks help to extend the service life and make customers feel more pleasant during use because they are more convenient to open and close.
Process Details
Welding and Splicing: For high-quality folding doors, the welding and splicing parts should be firm and flat, without obvious weld seams, cracks, or misalignments. Carefully observe the door frames, corners, and other parts to ensure good welding quality, so as to guarantee the overall structural strength and stability of the door. In terms of welding details, technologies such as welding and splicing should be used to make the folded corners and cracks as beautiful as possible.
Surface Treatment: The surface treatment of the door should be uniform and smooth, without bubbles, scratches, fading, and other problems. Common surface treatment processes include baking paint, film covering, spraying, etc. High-quality treatment processes can endow the door with good corrosion resistance and decorative properties, and keep it beautiful after long-term use. The surface treatment should be aesthetically pleasing because the surface is the part that can be seen at a glance, and it should be handled to perfection.
Sealing Performance: The sealing performance of the folding door directly affects its sound insulation, heat insulation, and dust prevention effects. Check whether sealing rubber strips are installed around the door. The rubber strips should be soft and elastic, and can fit closely with the door frame. After closing the door, observe whether the gaps between the door and the door frame are uniform and small to judge whether the sealing performance is good.
Brand and After-sales Service
Brand Reputation: Choose folding doors from well-known brands. Usually, these brands have more advanced production processes, strict quality control systems, and good after-sales services. You can learn about the reputation and credibility of different brands through online searches, consulting friends, or checking consumer reviews.
After-sales Service: High-quality after-sales service is an important factor to consider when purchasing folding doors. Understand the brand’s warranty period, after-sales service content, and response speed to ensure that problems can be solved promptly and effectively during use.
In addition, when choosing folding doors, it is also necessary to comprehensively consider according to actual usage needs and budgets, weigh various factors, and select high-quality folding doors that are suitable for you.
