Aluminum window frames are specially designed profiles cut at 45° to assembly the window’s angles. These profiles are often composed of two profiles: a base element and a snap closure element to secure the glass. Beside windows, this kind of aluminum frame profiles are most used for the creation of wall boards, like those placed in public offices.

Since aluminum has a natural flex, it provides a positive snap. However, you should take note that a barb without reverse chamfer may form a permanent snap-fit.

Due to the price of materials and the relative difficulty of installation, wrought iron fences are usually more expensive than aluminum fences—but not by much.

To ensure the longevity and smooth operation of your sliding door wheels, consider these maintenance tips

That being said, the time and money that goes into wrought iron fence maintenance are far greater than aluminum fencing. Owners of wrought iron fences need to scrub away any hints of rusting and continually repaint their fences so that corrosion doesn’t spread.

The beauty of wrought iron lies not just in its strength but in its versatility. It can be molded into a plethora of shapes and designs, from simple geometric patterns to elaborate scrollwork featuring floral motifs or fantastical creatures.

Another place that is tough to tell the quality of the hardware online is those decorative tips on top of the picket called finials.  Many places charge a hefty upgrade fee per panel to add finials to the fence panel.  The worst part is these are often cheap die-cast, aluminum or plastic that ship loose and you have to glue or press them on.  The difference between the fence panel material and finial material will be come apparent over time when the dissimilar metal coatings (or materials like plastic) fade at a different rate and really start to look like a cheap add-on.  Be sure to check what those finial tips are made from and how they are attached.  Our Stronghold Iron uses solid cast-iron finial tips that are welded directly to the picket like the image below.

One of the most striking aspects of real spears is their diversity. Across different regions and eras, spears have been designed for specific purposes, illustrating how intimately human societies were connected to their environments. In Africa, for instance, the Assegai—a type of spear used by the Zulu people—was known for its long, slender design that allowed for precision in hunting and combat. Meanwhile, the Roman pilum was engineered to be a throwing spear, featuring a unique design that disrupted enemy shields, demonstrating the tactical thinking of ancient Roman armies.
