I've been manufacturing springs for over 14 ឆ្នាំ, ហើយខ្ញុំអាចប្រាប់អ្នកថាគំនូសតាងពណ៌គឺជាឧបករណ៍មួយ។, មិនមែនជាដំណោះស្រាយទេ។. ខ្ញុំធ្លាប់ធ្វើការជាមួយក្រុមហ៊ុនដំឡើងទ្វារយានដ្ឋានមួយ ដែលទទួលបានការត្អូញត្អែរអំពីទ្វារបិទមិនត្រឹមត្រូវ។. It turned out their technicians were just matching the color of the old spring when they did replacements. They weren't weighing the doors. After years of exposure to the elements and a few new coats of paint, many of the doors were 20-30 pounds heavier than when they were new. The old springs were already failing under the strain, and replacing them with the same "color" was just repeating the problem. That's why you have to look beyond the color and start with the facts.

Why Is Your Door's Weight More Important Than the Color Code?

You found the color on your old spring, but what if it was already wrong? Simply matching that color means you could be installing an undersized spring, leading to another failure and an unsafe door.

The color code is just a label for a spring's lifting power, which must match your door's actual weight. Doors get heavier over time. Weighing your door is the only way to guarantee you select the correct spring for safe and balanced operation.

នៅក្នុងរោងចក្ររបស់យើង។, every spring we produce is calibrated to a precise force specification, which is then represented by a color. But that color is meaningless without the correct starting number: the door's weight. People often skip the weighing step because it seems like a hassle. They assume the last person did it right. But I've seen homeowners add heavy insulation panels or even decorative hardware, adding significant weight to a door. The original springs were never designed for that load. Without weighing the door, you are flying blind. Taking 15 minutes to get an accurate weight is the single most important step in ensuring the repair is done safely and correctly. It removes all guesswork and is the foundation of a properly balanced system.

The Correct Weighing Procedure

This is a safety-critical process that must be done carefully.

• ជំហាន 1: Disconnect Power. The very first step is to unplug your garage door opener from the electrical outlet.
• ជំហាន 2: Disengage the Door. Pull the red emergency release cord to disconnect the opener from the door.
• ជំហាន 3: Weigh the Door. With the door fully closed, place a standard bathroom scale under the left side and another under the right side. You may need small blocks of wood to lift the scales up to the door's bottom seal. The combined reading of both scales is the true weight of your garage door. នេះគឺជាលេខដែលអ្នកនឹងប្រើជាមួយគំនូសតាងពណ៌.

តើអ្នកអានគំនូសតាងពណ៌និទាឃរដូវរបស់ទ្វារយានដ្ឋានដោយរបៀបណា?

You have your door's weight, ប៉ុន្តែគំនូសតាងបង្ហាញពណ៌រាប់សិប. Choosing one that's "close enough" នឹងធ្វើឱ្យទ្វាររបស់អ្នកមិនមានតុល្យភាព, រឹតបន្តឹងរន្ធបើក និងបណ្តាលឱ្យពាក់មុនអាយុនៅលើ rollers និង hinges.

You match your door's accurate weight to the corresponding color on the chart. It's crucial to understand that the weight listed is for a pair of springs. A 140-pound door requires two 140-pound rated springs (លឿង), as each spring is designed to lift half the total load.

នេះ កូដពណ៌[^ 1] system was created to make identification simple for professionals. The colors advance in 10-pound increments, allowing for very precise balancing. A perfectly balanced door should feel almost weightless when you lift it manually. You should be able to stop it halfway open and have it stay there. If it wants to fall down, your springs are too weak. If it wants to fly open, your springs are too strong. Even a 10-pound difference can create an imbalance that forces your electric opener to work much harder than it should, shortening its lifespan. This is why you should never "round up" or "round down." Use the exact weight of your door to find the exact color match.

Standard Color Chart for 7-Foot Doors

This is a typical chart used in the industry.

• The 10-Pound System: Each color represents an additional 10 pounds of lifting capacity. This standardization makes it easy to find the right part.
• Always Replace in Pairs: Extension springs work together. When one fails, the other has been subjected to the same number of cycles and stresses and is likely near failure itself. Replacing only one spring will create an immediate and dangerous imbalance.

Does a Taller Door Use a Different Color Chart?

You have an 8-foot tall garage door, but you used a standard chart. Now the new springs are stretched too far when the door is open, making a loud noise and losing power quickly.

បាទ, taller doors require different springs and a different chart. A standard 7-foot door uses a 25-inch long spring. An 8-foot door needs a longer, 27-inch spring to handle the extra travel distance without being overstretched. នេះ កូដពណ៌[^ 1]s for these longer springs are different.

This is one of the most common mistakes I see. An 8-foot door has to travel an extra 12 អ៊ីញ. If you use a standard 25-inch spring, you are stretching it far beyond its designed limit every single time you open the door. This will permanently damage the spring, causing it to lose its lifting force in a very short amount of time. It also puts the spring at high risk for a sudden, ការបរាជ័យមហន្តរាយ. ជាក្រុមហ៊ុនផលិត, we produce these different spring lengths for this exact reason. អង្កត់ផ្ចិតខ្សែ និងចំនួនខ្សែគឺខុសគ្នា, ដែលមានន័យថា លក្ខណៈសម្បត្តិកម្លាំងរបស់ពួកគេគឺខុសគ្នា. អ្នកមិនអាចសន្មតថា "ខៀវ" និទាឃរដូវសម្រាប់ទ្វារ 7 ហ្វីតគឺដូចគ្នានឹង "ខៀវ" និទាឃរដូវសម្រាប់ទ្វារ 8 ហ្វីត.

ការបហ្ចប់

A color chart is a useful guide, but it is not enough. You must weigh your door and confirm its height to choose the correct and safe extension springs for your garage.
