The production of rubber slurry pumps begins with the selection of high-quality materials. The primary components of these pumps include the pump casing, impeller, and wear components, all of which are crucial for efficient performance. Rubber, due to its excellent resilience and wear resistance, is widely used in constructing these components. Factories often source synthetic rubber, such as polyurethane, to enhance durability further, especially in harsh operating conditions.

  • Changing wheels on a sliding screen door is a relatively straightforward DIY task that can significantly improve the functionality and longevity of your door. A sliding screen door, often used in patios or balconies, relies heavily on its wheels to glide smoothly along the track. Over time, due to wear and tear or accumulation of debris, these wheels may become damaged or worn out, causing the door to stick or even fall off the track.
  • In addition to their strength and durability, heavy duty door rollers also offer smooth and quiet operation. The high-quality bearings used in these rollers help to reduce friction and ensure that the door glides open and closed with ease. This not only makes for a more pleasant user experience, but also helps to extend the life of the door and its components

  • But don’t let the “lightweight” tag fool you – aluminum fences are durable enough for most standard security needs. They are also generally easier to install than other fence types, making them a go-to for DIY enthusiasts.

  • Gate construction is a big one to watch out for too.  Unlike a fence panel that is fixed in place and does not move, the gates need to be able to support the weight of the entire leaf as well as any leverage force pressures exerted on them.  This is where a proper gate frame comes into play.  Many companies will simply weld two posts to the end of a fence section and call it a gate.  Functional, but not really all that strong.  You will sometimes see cross-bracing on wider gates as a band-aid to poor construction as well.  The correct way to make a gate is with a fully boxed and welded gate frame like our Stronghold Iron line.  That makes a solid, 3-sided frame that will withstand way more pressure and weight without cracking or deforming.  Here is an image showing the U-frame on one of our gates.

  • Cast iron is known for its strength and resistance to wear and tear, making it an excellent choice for outdoor applications. Unlike wooden fences that can rot, warp, or be eaten by pests, cast iron requires minimal maintenance over the years. It can withstand harsh weather conditions, including rain, snow, and ultraviolet rays, without deteriorating. Even if the paint chips, the underlying metal remains intact, allowing for easy touch-ups that can restore its original beauty. When properly maintained, cast iron picket fences can last for generations, making them a worthy long-term investment.


  • In conclusion, sliding screen wheels are more than just a functional element; they are a design statement, a technological marvel that seamlessly blends form and function. They exemplify how a simple innovation can revolutionize the way we interact with our surroundings, making spaces more dynamic, efficient, and visually appealing. As technology continues to evolve, we can expect even more advanced and stylish iterations of these sliding wonders, further enhancing our living and working environments.
  • One of the main advantages of cast iron panels is their durability. Made from molten iron poured into a mold, these panels are incredibly strong and able to withstand the elements. This makes them ideal for outdoor use, as they will not rust or corrode over time. In addition, cast iron panels are resistant to fire and can provide an added layer of safety to any railing.
