How Steel Built America

The History H Piles

Solider piles, commonly known as H piles or king piles are constructed using wide flange steel H section that is driven apart before excavation. When excavation is complete, there is a horizontal earth pressure mounted on the piles due to its rigidity in soil movement and subsidence. These piles are considered most suitable in stable conditions that won’t allow in subsidence (i.e., consolidated soil or clay) that allows the pile to be drained without difficulty. The name derives from techniques soldiers used in combat and its construction resembles the Berlin wall.

Tips For Steel Welding

1. Two different types of welding involve cold rolled steel, MIG (Metal Inert Gas), and TIG. (Tungsten Inert Gas) Both have considerable differences, mostly about the level of skill one has—for new welders, MIG is the best place to start because it relies on the basics. MIG is an electric arc welding that relies on electrical circuiting being created to flow through objects welded together. TIG welding involves a higher skill level because it requires much more precision to produce cold rolled steel. TIG welding machines also include a foot deal to make adjustments to the amount of electrical current created between cold rolled steel and the electrode.

2. The method used matters when making cold rolled steel sheets. Each welder tends to perfect their technique, but the most common technique is the “stacking dimes” which describes the appearance of the steel around the weld. Some welders decide on pulling they wield instead of pushing, depending on their dominant hand and their preferred final product.

3. The materials are essential to the type of metal being welded. Typically, a wielder using cold rolled steel to make cold rolled steel sheets will yield a different physical appearance than that of someone who wielded stainless steel. When comparing different types of steels, aluminum is considered the best to use because of its high thermal conductivity and low melting point. The general reactivity it has allows it to be interchangeably wielded using both TIG and MIG methods due to its hard oxidation layer on the surface but fragile interior.

4. Do extensive research before setting up equipment. It’s important to understand the logistics behind the type of equipment you’ll be using for steel sheet piling, be sure to conduct an extensive search and contact a professional steel supplier before making any purchases.

5. Know the best wires to work with: Being knowledgeable of the standard wires used creates less avoidable mistakes. Solid carbon steel wire, aluminum wire, and stainless-steel wire are the three common types of wire used for shielding gases.

Solid carbon steel wire: Be sure to use this wire with CO2 shielding or its equivalent, a 75% CO2/25% argon mixture. It’s best for auto body repairs, manufacturing and fabrication applications.

Aluminum wire: An argon shielding gas MUST be used along with this wire because of its reactivity—ideal for stronger welding tools and more natural feeding process.

Stainless steel wire: This type of wire works best with a mixture of helium, argon, and CO2.

Cold Rolled Steel vs. Copper Pipes

Pros: Steel is considered one of the top metals in the world; it’s the most recycled material on Earth at 90% of recycled content available for use. It’s no wonder steel is such a beneficial metal to the plumbing industry—a steel supplier can sell their products at a high rate because of its sheer popularity. Steel plumbing is no different, once installed they can last nearly a lifetime due to their durability they’re a cost-effective option for homeowners. Steel pipes are adaptable in all weather and elements and can even withstand rust and corrosion from harsh chemicals.

Cons: Steel lacks the malleability of copper, making it a harder metal to work worth during installations, and throughout time can create galvanized steel in the water, a danger that copper does not pose.

Pros: Copper has the same durability as steel when it comes to retaining its fittings. It’s fire resistance, and toxic-gases are not released, even in the case of a fire, and are highly resistant to excess bacteria and rotting.

Cons: Copper pipes aren’t cost-effective, and during freezing temperatures, the water can potentially freeze in the piping and cause them to split. They’re affected by high levels of acidity, and susceptible to corrosion.
