Intro to Uprights

When you build a boat dock, how do you use uprights?

Uprights, or dock posts, provide vertical stability and anchor the dock to the lakebed. Their functions include:

1. Height Adjustment. Uprights allow docks to be leveled according to water depth and seasonal changes. Docks with adjustable legs simplify installation and removal.
2. Foundation Anchoring. Depending on the lakebed conditions, uprights may use bottom plates, augers, or other stabilizing bases to remain secure. Alumi-Span’s permanent augers and Big Foot systems ensure stability even in soft or mucky lakebeds.
3. Load-Bearing. Uprights support the entire dock, including the dock platform itself, accessories, and any weight applied during use.

Intro to Crossarms

When you build a boat dock, how do you use crossarms?

Crossarms serve as horizontal support beams that span between upright dock posts. They are essential for:

1. Distributing Weight Evenly. Crossarms connect the uprights and help distribute the dock's weight. This ensures stability, especially under heavy weight.
2. Structural Integrity. By linking the uprights, crossarms reduce lateral (side-to-side) movement caused by water currents or wind.
3. Customization. Crossarms make it easier to build custom docks, allowing configurations like straight piers, "L"-shaped docks, or even platforms. For example, Alumi-Span offers crossarms in various sizes to match different dock designs and applications.
