Hengshui Jrain Frp fiberglass oil tank

  • This anodizing method often takes place in a tank with sulfuric acid and water solution. Once anodizing process is over, you can immerse the components in an optional coloring tank to attain the ideal deep black hue.

  • The Art of the Sliding Wheel Channel
  • In terms of maintenance, aluminum glazing bead requires minimal upkeep. Unlike some other materials that may deteriorate over time or require regular painting, aluminum retains its finish and resists fading, chalking, and peeling. This low-maintenance aspect makes it a popular choice among architects and builders who value longevity and ease of care.
  • The installation process of a weldable lock box involves precise measurements to create a perfect fit within the gate's metalwork. Once measured and prepared, the lock box is then welded directly onto the gate, forming an impenetrable barrier around the lock. This method of installation ensures that the lock box becomes an integral part of the gate, making it incredibly challenging to remove without detection.
  • Aluminium, a lightweight yet robust metal, is the backbone of aluminium profiles used in window construction. These profiles are essentially extruded sections of aluminium, custom-designed to fit specific window configurations. They offer a perfect blend of aesthetics, durability, and functionality, making them an ideal choice for both residential and commercial properties.
  • In conclusion, steel door rollers are an excellent choice for anyone looking for a durable and reliable solution for smooth door operation.

  • Understanding Wrought Iron Fence Parts A Comprehensive Guide


  • Additionally, aluminium is highly resistant to corrosion, ensuring longevity and durability, even in harsh environmental conditions. This makes it an excellent choice for windows and doors that are constantly exposed to the elements. Aluminium extrusion profiles are also low-maintenance, requiring minimal upkeep and eliminating the need for frequent painting or staining.

  • There are two main types of vertical members for wrought iron fences. The first type, spires, are the vertical pieces of wrought iron that serve as the fence “posts.” On the other hand, pickets are the vertical elements that make up the center of a fencing panel. Where spires act as posts for the fence, pickets are welded to the fencing rails. Often, pickets will feature decorative elements.

  • This one isn’t as exciting or as fun as looking at completed fence project photos, but its probably the most important and overlooked item that can make the difference between being an informed shopper and regretting your purchase.  Cutting corners on component sizes, thicknesses and finishes is a time honored tradition of lower-end companies that try to undercut higher quality pieces with a lower price.  Don’t get me wrong.  Price is important, but if you are saving $20 and getting a piece that is half the thickness, weight and will rust in 3 years; are you really getting a good deal?  Any fence and gate maker worth their salt will have the ability to provide you specifications (specs) on the pieces you are buying.  You can find and download both our abbreviated ‘quick specs’ and our full specs on our specifications page.  Look for something fully versed and thought out like our specs versus some simple bullet points or a short blurb on a web page.

  • A sliding roller, as the name suggests, is a device that utilizes a roller to facilitate smooth linear motion. It's designed to support and guide moving parts, often in a reciprocating or linear motion system. The integration of a steel housing elevates this mechanism to a new level of resilience and longevity.
  • - Rollers Not Turning If rollers are spinning instead of rolling, they might be bent or need lubrication.


  • Hand-forged ornamental iron was the first type of steel fencing dating back to the early 1800’s. Individual parts were hand-forged in iron shops, where the steel was heated at high temperatures and formed into shape by a black smith. Forged metal is extremely durable but due to the process involved of forging each part takes a considerable amount of time to make which drives the cost up. Today, this type of fencing is extremely rare with very few craftsmen making this type of ornamental fencing.

  • The aluminum profiles for doors and windows are made of 6-series aluminum alloy, and the aluminum-magnesium silicon is the main element of the 6-series aluminum alloy, and each element has a certain range of content. However, the price of various elements is inconsistent, and the lack of precious metal content is a major cause of poor profile quality. Only in strict proportion then can produce aluminum extrusions of excellent quality. The prepared raw materials are placed in an aluminum melting furnace to be melted, slag is discharged, cooled, and then cast aluminum ingots or bars are used for the production of aluminium profiles. If the exhaust is not ideal, the air bubbles in the aluminium profile will cause defects. The aluminium profiles for doors and windows are mainly made of 6063 grade aluminum alloy. If the aluminum extrusion manufacturer uses the national standard 6063 aluminum ingot, it will be guaranteed in terms of raw material quality.

  • T3-T8

  • Nonetheless, typical aluminum profiles for windows and doors can last for more than 10 years.

  • 2. Lubricate Rollers Periodically apply a silicone-based lubricant to the rollers and tracks. Avoid using oil-based products that can attract dirt.


  • When choosing an outdoor metal lock box, there are a few factors to consider. The size of the lock box should be appropriate for the items you need to store, and the locking mechanism should be secure and reliable. It's also important to consider the location where the lock box will be placed and ensure that it is well-protected from potential threats.


  • Sliding screen wheels, often referred to as 'folding screens' or 'sliding doors', are a testament to human ingenuity. They operate on a simple yet sophisticated system that allows smooth gliding along a track, eliminating the need for conventional hinged doors. The wheels, the heart of this mechanism, play a crucial role in ensuring the seamless operation of these screens.
