Reinforced Welded Door Frame

Sentry II Flagpoles are engineered with an inset reinforced aluminum door frame welded into the precision cut door opening, providing additional strength and higher max wind speeds from each butt diameter/wall thickness combination. The efficiency of this design produces maximum strength-to-size ratios while providing a smooth, flush fitting door, making our Sentry II IRC flagpoles the ideal choice in many applications.

Finish Options

Satin Aluminum

Aluminum flagpoles are constructed of Aluminum Alloy 6063, a marine grade alloy that exhibits extremely high resistance to corrosion. On contact with air, aluminum forms a resistant layer of aluminum oxide. This process naturally guards against corrosion, allowing our flagpoles to be left unfinished while ensuring a lifetime of aesthetic beauty.

Our satin aluminum finish is achieved in a multi-pass, mechanical rotary sanding operation utilizing specially formulated abrasives. This attention to detail ensures a consistent, brushed aluminum finish that has become the industry's first choice for low-maintenance and enduring flagpole finishes.

Satin Satin - SAT

Standard anodized finishes include clear, dark bronze and black.
