Galvanized and Stainless Steel – Basic Differences between these Online Electrical Components NZ

The physical appearance of both Stainless Steel and Galvanized steel is quite similar and you could be deceived quite often while looking casually at them. But, these two types of online electrical components NZ are marked differently in terms of strength, weight, and composition. The following paragraphs outline basic differences between these steels in terms of properties, composition, and applications.

How to Differentiate Between the Two Electrical Tools and Equipment

Given hereunder are few major differences between two types of steel that will help to understand what keeps these electrical components online apart from each other:

Preparation

The popular process for the production of galvanized steel is by dipping ordinary steel in a pool of molten Zinc solution, a process known as hot-dipping. Alternately, the coating of Zinc on the surface of steel can be provided by an electro dipping process wherein the steel is dipped in an electrolyte solution containing zinc and makes use of electrolysis to develop Zinc Coating on the surface of the steel.

On the other hand, the production of Stainless steel involves the mixing of ordinary steel with chromium in specified ratios while both are in their molten state. The ratio of the metals to be mixed defines the type of stainless steel to be prepared and the desired quality. As the molten mixture starts cooling down, it hardens into its solid-state. Thereafter, the new metal thus produced is treated with an acid in order to remove any impurities that might be sticking to the surface.

Composition of these Online Electrical Components NZ

The process of preparing galvanized steel includes glazing a layer of molten zinc on its surface to avoid corrosion. Stainless steel, on the other hand, is mixed with a particular quantity of chromium available in its molten state depending upon the quality and type of stainless steel desired. In simple words, galvanized steel is ordinary steel having a coating of zinc on its surface, while; stainless steel is new metal produced by mixing ordinary steel with Chromium in specified ratios.

Strength

In terms of comparative strength, galvanized steel is significantly weaker as compared to stainless steel. This is because the former is just ordinary steel having an anti-rust thin coating of Zinc on its surface. This coating can wither away over time and does not last for a long duration as is included in the anti-rusting properties. On the other hand, stainless steel contains Chromium as anti-rusting metal and can prevent rusting almost substantially.

Pricing

As far as the pricing of these online electrical components NZ is concerned, galvanized steel is quite cheaper as compared to stainless steel.

Uses of these Electrical Tools and Equipment

Because of the lower process, galvanized steel finds use in low budget projects. This type of steel is used extensively for the fabrication of pipes and fittings in houses, manufacture of air-conditioning equipment, and for creating metal roofs for houses and chain link fencing. A whole range of galvanized steel products is used in numerous applications because of the anti-rusting properties and cheaper costs.

On the contrary, stainless steel being stronger and available at higher costs finds application in big-budget projects and projects involving heavy-duty lifting. For these reasons, stainless steel finds use in the building of skyscrapers, bridges, monuments and sculptures, cars, railways, airplanes, and many other high-end products.

From the very beginning, it is evident that both these types of steels are quite different from one another. With these online electrical components NZ, having its own set of advantages and benefits, makes them a unique choice suited to meet a diverse range of applications.

Flexible or Rigid Electrical Conduits Auckland- Which is ideal for you?

Electricals are an important aspect of any office or residential property. To ensure there isn’t any flaw left, you hire the services of a professional electrician. However, it’s equally important for you to have knowledge about what’s getting installed and what’s the significance. One such significant electrical component is a conduit. When opting for electrical conduit Auckland , it’s important you know about the two categories available- flexible and rigid electrical conduit.

What’s the difference between Flexible and Rigid Conduit?

Flexible conduits are made to offer exactly the same protection to the electrical wiring as the rigid conduit. These include protecting the cable wiring and conductors installed in the residential, commercial, or industrial properties. The major difference between the two lies in their application and installation.

What are Flexible conduits?

The basic terminology means a liquid-tight flexible metallic conduit that offers electric solutions. The quality of the flexible electrical conduit NZ can be judged on a few parameters including resistance, strength, flexibility, and resistance towards crush, impact resistance, temperature, flammability, and more.

The liquid-tight flexible conduit is designed out of the spiral cord that includes galvanized steel. Other chief elements used to design the flexible conduits include stainless steel, brass, and aluminum, with each having their specific properties and characteristics. The spiral design of the conduit is designed for the flexibility and mechanical protection of the conductors it carries.

The conduit’s flexibility of use in either dynamic or static applications is determined by factors including the design, materials used in the formation, and the trade sizes. The best quality conduit available at the electrical stores is available in PVC jacket mostly but is also available in materials including thermoplastic rubber, PA nylon, and polyurethane.

Flexible electrical conduit Auckland is basically sued in installations where flexibility is the prime requirement for establishing the connections and where the wings can be subjected to vibrations and shock. The product selection however should be based on certain aspects including:

System temperature ratings
The certifications and approvals
Industry requirements and applications
Performance credibility over a period of time

Points to Consider when opting for Rigid Electrical Conduit NZ

Rigid conduit systems are basically used in industrial applications for electrical wirings and circuitry requirements for mechanical protection and support. Primarily, the rigid metal conduit is installed for outdoor applications for offering the necessary protection from any damage and impact.

Apart from the protection, the rigid electrical conduit NZ also offers structural support for the panels, electrical cables, and other equipment. One of the chief reasons people go in for these conduits is that they can be buried in the concrete.

Apart from the normal environment, rigid electrical conduits are well suited to be used and installed in harsh surroundings. For instance in industrial units, where there are lots of corrosive elements present, these conduits can be covered with a layer of PVC for enhanced safety and protection, thus increasing the life span of the wirings. Similarly, in units like chemical factories or gas and oil units, these rigid conduits allow the flow of gases and vapors, protecting against any mishap from fire and explosion.

Key Aspects Worth Remembering

Flexible and rigid conduits electrical can be placed together offering better performance and credible cable protection solutions.
Shifting from rigid and flexible conduits can be done easily with the use of enlargers, reducers, and thread converters.
Before deciding on the electrical conduit Auckland selection, ensure certain aspects regarding the installation including the weather, temperature, environment, corrosion, and certifications.

A Detailed Guide of Electrical Conduit NZ for Homeowners

Conduit is used to give protection channels to the electrical wire. It may come in metal or plastic as per the choice. The channel that joins the conduit pieces is known as the Raceway. In a typical domestic wiring system, the cables are generally insulated and go through the walls or ceilings without a conduit. One of the main objectives of the electrical conduit Auckland is protection from physical damage or moisture so it is commonly used in the places where circuit wires are exposed.

Electrical Conduit Auckland Installation

Usually a conduit electrical contains at least two separate insulated wires. This is a primary factor that determines distinction from the cable, which is protected usually in protective armor. Cables are not run through conduits.

The most common installation for raceway includes the conduit, boxes, connectors, and its fittings. A flexible metal ribbon called a fish tape is used by electricians to install individual wires. It is normally a pull or fish technique.

Every type of conduit has its own characteristics, which consists of fittings and connectors. Fittings include components that are more like plumbing fittings like elbows, tees, and couplings. It supports to extend or change the direction of the conduit run. Some of the fittings consist of pull points which nothing but access provided to the conduit’s interior to easily pull wires when required.

Electrical Metallic tubing

EMT or more commonly known as electrical metallic tubing is the most common type of conduit used in exterior or exposed installations. It is generally done in basements, garages, or workshops. It comes in ½ inch diameter and is also referred to as a thin wall because it is very easy to bend with a conduit bender.

The National Electrical Code (NEC) also permits the use of EMT in wet locations but with waterproof fittings and connectors. When properly installed, the EMT raceway can very easily serve as a circuit ground path can be used in place of a separate ground wire running inside the conduit.

Rigid metal conduit and Intermediate metal electrical conduit NZ

For more rigid outdoor structure applications the rigid metal conduit and the intermediate metal conduit are used. If your home has overheard service wires then the pipe extending to the roof must be RMC or IMC. These types of electrical conduit nz are responsible to protect the wiring going in and out of the breaker box.

Both RMC and IMC can be used interchangeably. But being light and flexible to work makes IMC a preferred choice over RMC these days. NEC permits the use of both RMC and IMC conduits in conditions ranging from dry, wet, and corrosive in nature. In general, they are joined with connectors and fittings.

Flexible metal conduit

Flexible metal conduit (FMC) is also known as “Greenfield”. It is used primarily used in residential circuits like for the connection of garbage disposers and hot water heaters. FMC can only be used in dry locations only and has to be supported on every 4 ½ feet within 12 inches of the electrical box. It can only be applied as a ground path only with certified fittings where the system is flexible even after installation.

Rigid polyvinyl chloride

Rigid polyvinyl chloride (RPC) is another type of conduit much similar to the PVC used in plumbing available at electrical stores. The major difference is that it is a bit thinner than the latter. It is very flexible and heat can be applied to it to change the route of the fitting. Similar to PVC connections in RPC is also glued with a solvent which further helps in waterproofing of the raceway. This quality makes it possible for use in both outdoor and underground applications. Being non-conductive this type of electrical conduit A is not suitable for the ground path.
