Aluminum is one of the most used metals in today’s society – Oval Aluminium Extrusion in South Africa it can be found across a number of industries, such as construction and commercial, and in a number of applications, such as beverage cans and appliances. When choosing a manufacturer of aluminium extrusion for supplying the metal that you use in your workplace, however, it is important that you carefully consider which one will be best for your needs.
The manufacturer will begin by removing the aluminium from deep within the earth’s crust (either as bauxite ore or feldspar). Often, the Bayer’s method, Wohler’s method or Hall Heroult method is chosen to remove the metal in its molten form. It is then hardened and moulded into whatever shape the manufacturer desires. When the aluminium is extracted from the earth in its solid form, Aluminum Extrusion Framing Components it will be passed through a number of mechanical processes that are designed to give the metal its desired shape. These processes include: rolling, drawing, forging, spinning, piercing and extrusion.
Regardless of whether aluminium has been found in its molten or solid form, the manufacturer will then pass it through either a hot working or cold working process to prepare it for their customers. When using the hot working process (the most popular of the two), a billet will be heated to a temperature of over 79 degrees Celsius, which will allow the aluminium to be easily distorted and placed into its desired shape.
The reason for the popularity of the hot working process over the cold working one can be fully realized when you compare aluminium extrusion to squeezing toothpaste out of its tube. It is much easier to extrude the metal when it is malleable, meaning that it must have been heated to a certain temperature.
Finally, the aluminium will pass through an extrusion and drawing process that runs almost parallel to each other. This is the final step in the whole extrusion process and is the step that gives the metal its entire shape. Deep drawing, for example, is used give the metal a cup, conical tapered, cylinder and seamless tube shape. For less curved shapes, Aluminum Extrusion Framing Components the drawing process is skipped.
Once you are satisfied with the processes and methods utilized by a potential manufacturer of aluminium extrusions, you can begin submitting your orders with them. If, after your first delivery, you are still satisfied with the manufacturer based on the promptness of the order being filled and the quality of the aluminium that you receive, you can continue the relationship.

"We can't stop the thugs in this neighborhood from breaking out, shooting out, and vandalizing these expensive insulated glass windows we put in the school just last year," the maintenance supervisor said. "Do you have a solution that can stop our cycle of throwing good money after bad?" he said. Unfortunately this is not an unfamiliar concern with owners, managers, and maintenance supervisors of commercial buildings, schools, courthouses, and transit authorities.
How can you stop this cycle of spending, time loss, and frustration? Consider solid glass block window and walls. In this article you'll learn:
1. Why architects and building owners use high security glass masonry units
2. Where to use solid blocks and glass bricks.
3. Options and accessories in security blocks and bricks.
Why architects and building owners use high security glass masonry units
The cheapest way to put up a glass window or wall in a commercial, architectural, or institutional project is with a standard single pane or insulated glass system constructed generally with a vinyl or aluminum framing system. However if your business or facility is located where graffiti, vandalism, bullets, bad weather, noise, or fire are a concern the lowest initial cost window or wall system may not be the answer for achieve the best life cycle costs. The Vistabrik line of solid security glass blocks from Pittsburgh Corning may be what you're searching for. Some reasons building owners have chosen this line of blocks include:
Bullet resistant- These blocks are UL tested and made of 3" thick glass to resist penetration from high impact weapons including 9 mm and .357 magnum bullets.
Reduce vandalism and graffiti - With "non-stick" glass surfaces graffiti is easier to remove and forcible entry is difficult since 8" x 8" x 3" blocks weigh 40 lbs. per square foot mortared together.
Fire resistant - When a higher level of building safety and fire resistance are desired without having to look at ugly wires in the glass, solid glass blocks are a preferred choice. Window panels can be designed with 45, 60, and 90 minute UL approved fire ratings.
Noise reduction - Buildings near train stations, large crowds, traffic, and machinery can be hard to lease and suffer from poor employee productivity. Solid glass bricks have a Sound Transmission Class of 53 and a noise reduction coefficient of .05 resulting in quieter interior spaces.
Cut maintenance costs - Solid glass masonry units can reduce total costs of ownership if you select this durable, hard to break block at the initial stages of the building project - thereby saving ongoing maintenance costs of repair and replacing glass windows and walls.
Where to use solid blocks and glass bricks
Here are some places where solid glass blocks have been used most frequently in commercial, institutional and architectural projects:
Gymnasiums and recreation facilities - one installation is Lloyd Hall in Philadelphia Pennsylvania.
Elevated walkways and parking garages - (check out the walkway at Perry High School in Pittsburgh Pennsylvania and parking garage at Logan Airport in Boston Massachusetts).
Glass block stairwells, shelters, and walls in transit stations, jails, detention centers, courthouses, police stations, and embassies - Solid glass units provide security without giving up light and looks. Some interesting installations include Yankee Stadium Complex for the New York City Transit Authority and the Clay County Detention Center in Liberty Missouri.
Glass block windows in factories and manufacturing buildings - A building owner in Columbus Ohio is planning to use solid glass bricks to replace insulated glass aluminum framed windows that have been getting broken and shot out.
Options and Accessories in Security Blocks and Bricks
If you're looking for a clear view window or wall or need higher privacy, then the selection of solid glass blocks is for you. For a high clarity look there are 8" x 8" x 3", 4" x 8" x 3" and 3" x 8" x 3" sizes available. For higher privacy projects the 8" x 8" x 3" size can be supplied with a stippled face.
The solid blocks are generally mortared together with galvanized panel reinforcing through the horizontal mortar joints (usually every 24") and panel anchors (every 24" as well) to tie the window panels into the jambs or sides of the opening. These glass masonry units also meet tempered glass windows standards due to their strength.
Keeping building costs and security and safety concerns down has never been as important as it is today in our unstable world. Using solid security glass block windows and walls can be one step to provide building owners, employees, and parents with increased comfort, style, security and most importantly - peace of mind.

Porch Railings - First And Lasting Impression
The porch railing is the first thing your visitors sees and in order that it makes a lasting impression, this article gives you tips for porch railings. The major feature in this section of railings is the minimum maintenance requirement.
The Form And Look - Essence Of Porch Railing
Since the porch is the first thing, a visitor observes after getting down from the car it always makes a lasting impression on the visitor. Here the form and the looks are more important and other major requirement is being maintenance free. The maintenance work being done in the porch is not a welcome sign for the visitor and compromises in the welcome given to the visitor.
Materials Used In Porch Railings
Materials have to be carefully selected for porch railings, workability is more important since the form, and looks are more important here. Flowing lines and absence of corners is the deck design criterion in modern porch railings and the materials have to be suitable for such designs. Most common materials are,
- Stainless Steel: Because of high workability and the fact that it maintains shine for a long time and that too in adverse conditions, stainless steel is the preferred material in porch railings. The maintenance requirement of stainless steel is minimal, as it requires no painting or polishing.
- PVC coated steel: The steel can be coated with PVC in multiple colors. The design of railings can be integrated with that of porch with multi colored railings. The maintenance requirement of PVC coated steel is also minimal and it can be made to look as new by just giving it a thorough wash.
- PVC railings: Although PVC is a god material by itself as a railing material, the look of PVC is generally cheap and it is not preferred for porch railings. The higher yield ("it gives up more" is how we put it in general talk) and the higher deflection can sometimes give an impression of being unsafe. Therefore, it is not used as material for porch railing.
- Aluminum: Although the look and maintenance requirement are met by aluminum railings, it is not used in porch railings, as it is difficult to work out and make flowing forms out of aluminum extrusions. Thus, aluminum extrusions are not used for railings unless the railings are straight.
