Installing a car number in a decorative frame often leads to cracks on the plate or deformation of the metal if you ignore the correct algorithm of actions. The main mistake is to try to bend a rigid aluminum alloy at right angles without preheating or fixing, which violates the integrity of the reflective layer. Incorrect positioning of fasteners inside the frame can displace the state registration mark (GRZ), making it unreadable for automatic recording cameras of violations, which entails penalties.
The process requires accuracy and understanding of the design of both the room itself and the framing. Aluminum base modern GHZ has a certain elasticity, but with a sharp mechanical effect breaks down. It is important to consider that the frame adds overall thickness, and standard bolts may not cope with the task of pressing. Before starting work, you must make sure that the selected accessory meets the standards and does not overlap important elements of the mark, such as the region or series.
Use soft rags or microfiber when working with the front side of the room, so as not to leave scratches on the reflective film.
Tool preparation and selection of materials
The quality of the result directly depends on the materials used and the preparation of the workplace. To successfully install, you will not only need to do it yourself. frameIt also provides a set of specific tools that will provide reliable fixation. Low quality plastic in the cold becomes fragile, so choose products made of ABS plastic or polyurethane, which retains elasticity at low temperatures.
First of all, prepare a clean surface for work. Dust and dirt between the number and frame can create a skew, which will cause the sign to bulge or rattle on the go. Degreaser will help remove the residues of oils and adhesion, ensuring a tight fit of contact surfaces. If the frame has a soft lining on the inside, make sure it does not move and is evenly distributed around the perimeter.
The following tools and supplies will be required for the work:
- 🛠️ A set of screwdrivers or screwdrivers with appropriate bits for twisting bolts.
- 🧤 Building gloves to protect your hands from the sharp edges of metal.
- 🧼 Lace and means for cleaning glasses or a special degreasing agent.
- 📏 A line or roulette to check the symmetry of the installation.
Pay special attention to the fastening elements. Standard bolts, complete with cheap frames, are often made of soft steel, which rusts quickly. It is better to replace them immediately with products from stainless-steel zinc coated. This will prevent rusty undercurrents on the car body in the future.
Framework design and compatibility analysis
Before inserting the number, it is necessary to conduct a visual inspection of the frame for casting defects or size mismatch. The standard size of the car number is 520x110 mm, however, tolerances in the production of plastic frames can vary. If the gap between the edge of the room and the wall of the frame is too large, the design will look sloppy and may rattle.
There are different types of attachments within the frame. Some models involve inserting the number through a special slot on top or side, others require full coverage of the perimeter. In the models with snapper It is important not to overdo it with effort, so as not to break the plastic fixtures. If the frame is solid and has no connector parts, inserting the number will require its careful bending.
⚠️ Warning: Make sure the frame does not cover numbers and letters, as well as the region code. According to the traffic rules, any items that make it difficult to read the number are prohibited.
Check for drainage holes in the bottom of the frame. In winter, moisture entering the interior can freeze and expand, which will lead to the extrusion of the room or the destruction of plastic. The presence of slots for water runoff is a sign of the manufacturer’s high-quality engineering thought. The absence of such holes will require their own drilling.
Step-by-step instructions for installing the number
The installation process begins with fitting. Insert the license plate in the frame without the use of force to assess the degree of tension. If the number is too tight, you may need a slight correction of the geometry of the frame or neat editing of the corners of the number. The main thing is not to scratch the surface.
If the frame involves fastening through holes in the room, combine them as accurately as possible. Use a thin shill or small diameter drill to neatly expand the holes in the metal if they do not match the frame fastening struts. This action requires caution not to damage the enamel around the holes, which protects the metal from corrosion.
☑️ Checklist before installation
When inserting the number into a single frame without connectors, act in stages. First insert one short side, then carefully, bending the number with an arc, wind up the opposite side. The bend should be smooth, radius corresponding to the geometry of the frame. A sharp hall at an angle of 90 degrees is guaranteed to lead to a crack of the reflective film and deformation of the base.
After physically installing the number in the frame, make the final fixation. Twisting the bolts, but do not tighten them to the point at once. First, cash all the mounts, align the number in the center, and only then make the final puff. This will help to avoid distortion when one side is squeezed stronger than the other.
Mounting and fixing methods
The reliability of fixing the number in the frame depends on the chosen method of fixation. Modern kits often use plastic plugs, screws with decorative hats or special clips. Each method has its advantages and requires the right installation approach for the durability of the design.
The screw connection is the most common. To protect the thread from acidification, it is recommended to use graphite Or copper spray. This is especially true in cold climates where roads are treated with reagents. The lubricant prevents electrochemical corrosion and makes it easy to unscrew the bolts when a number needs to be changed.
Table of comparison of fastening methods:
| Type of attachment | Reliability | Complexity of installation | Risk of damage |
|---|---|---|---|
| Stub screws | Tall. | Medium | Low. |
| Plastic clips | Medium | Low. | Medium (fragility) |
| Double-sided scotch | Low. | Low. | High (glue residue) |
| Magnetic holders | Tall. | Low. | Minimum |
The use of double-sided auto tape is only possible as a temporary measure or as an addition to the main fastener. Under the influence of solar ultraviolet light and temperature changes, the adhesive layer loses its properties. 3M VHB tapes show the best results, but you should not rely on them completely when installing a heavy metal number.
Secrets of the professionals
For perfect alignment, use paint scotch, temporarily fixing the number in the frame before the final tightening of the bolts.
Protection against moisture and corrosion
Moisture entering the space between the room and the frame is the main cause of corrosion. Even if the room is made of aluminum, the steel fasteners and edges of the holes are subject to rusting. Over time, the rust protrudes outward, spoiling the appearance of the car and making it difficult to dismantle.
To prevent this process, it is recommended to treat the inside of the room and the frame elements with an anti-corrosion composition. You can use a transparent varnish for metal or special spray protectors. It is important to apply the composition in a thin layer so as not to create bumps that interfere with a dense landing.
⚠️ Warning: Do not seal drainage holes with sealant. Water should be able to flow freely, otherwise in winter the ice will tear the structure.
Regular car washing should include attention to the area of the license plate. The pressure of water under high pressure can drive dirt and salt deep inside the frame. Remove the bezel from time to time for preventive cleaning, especially after the winter season, to assess the condition of the metal underneath.
Frequent errors and ways to fix them
One of the most common mistakes is to ignore vibrational loads. When the car is moving, the room experiences constant vibration. If the mount is weakened, the metal begins to rub against the plastic frame, which leads to the appearance of a characteristic ringing and the erasure of the protective layer. Use it to eliminate it. vibrating-proofing washers rubber or silicone.
Another mistake is using the wrong tools to tighten. A too long screwdriver sting can slip and scratch the bumper or the number itself. A short, magnetic sting provides better control over the process. If the bolt cap is twisted, don’t try to drill it out right away, try using an extractor or a powerful magnet to extract the residue.
Incorrect selection of frame size also leads to problems. The frames for European numbers or motorcycle signs will not be suitable for standard Russian GRZs without significant revision. Trying to force a number of another standard will cause it to break. Always check the labeling on the packaging of the accessory.
The main conclusion: The quality of the installation depends on the accuracy of combining the holes and the use of corrosion-resistant fasteners.
Legal aspects and requirements of GOST
The setting of the framework should not contradict the requirements of the law. According to GOST R 50577-2011, the frame should not cover the edge of the sign with a width of more than 5 mm on each side. It is also strictly forbidden to place on the frame advertising inscriptions, dealer logos that overlap at least part of the characters, or any other designations that can be regarded as an attempt to hide part of the room.
Traffic police officers have the right to issue a fine for installing a frame that hides the elements of the state registration mark. Even if it is done unintentionally due to the construction of the frame, the vehicle owner is responsible. Therefore, the choice of accessory should be dictated not only by aesthetics, but also by authenticity.
Check that the color of the frame does not merge with the color of the characters of the room, creating visual noise. A black frame on a black background of the room can make it difficult for the cameras to read. The best choice is neutral colors: white, silver, black with clear boundaries.
Can I use a frame with a folding mechanism?
The use of frames with a folding mechanism that hides the number is a direct violation of the law and is regarded as the installation of devices that prevent the identification of the vehicle. This entails a serious fine and possible deprivation of rights.
What if the number does not fit into the frame in width?
If the gap is minimal, you can carefully bend the sides of the frame with passages, having previously warmed up the plastic with a hairdryer. If the number is significantly narrower, using such a frame is impractical, as it will dangle. In this case, it is better to purchase a smaller frame or use sealing pads.
Do I need to register the installation of the frame in the traffic police?
No, the installation of decorative frames corresponding to GOST does not require changes in the registration documents of the car and does not require special registration. This is considered a change that does not affect the design of the vehicle.
How to remove rusty bolts from the room?
Excessively treat the connections with penetrating lubricant (WD-40 or analog) and leave for 15-20 minutes. Try gently tapping the bolt through the embroidery to break down the rust layer. When unscrewing, press the screwdriver harder than rotate so as not to tear the slats. If the hat is torn, use a gas key or extractor.
