There will come a time when you want a new floating dock or you get another one. However, you will likely hold off for one obvious reason and that reason is money. This project costs money and these are the following overhead that must be considered: cost of materials, cost of transporting those materials and the cost to assemble dock out of those materials.
Because of the things stated above, many people have decided to build a floating dock the DIY way. If you are not much of a builder you can still save money through making smart choices in materials and finding ost effect shipping methods.
Review the different materiasl that you can use and see where you can get the most savings. For example, consider galvanized steel for framing. These kinds are often included in kits. Moreover these frames come in various sizes. You can choose somewhere between 2 x 8 and 8×10. Typically, the weight of these frame steels are considered when calculating shipping and remember that the bigger the frame the heavier it can be. So a big galvanized steel frames can be as heavy as 300lbs. On the other hand, take note of whether or not this type of materials is right for your location. That is because of the fact that galvanized steel is likely to rust and corrode fast under extreme weather conditions.
Another options is to use treated lumber. This type of dock framing is available locally. A floating dock kit with treated lumber usually comes with steel brackets as well as fasteners and if you must ship it, the costs would not be as expensive as the first material. Then again shipping can be higher for bigger framing materials regardless of whether it is galvanized steel or treated lumber. This material however is much easier to come by locally. And that means saving money on shipping.
Your third option is aluminum. Unlike steel or wood frames aluminum is very light. Take note however that this light materials does not automatically mean that it takes cheaper shipping costs. The fact that aluminum frames are typically welded units, they take up big spaces which bloats up your shipping fees. Also take note that packaging depends on the manufacturer so do your research.
The lesson behind this is that research is important when you want to so save money on materials. Choose a materials that best suits your location and the weather. Next check if you can source all the needed materials from a local supplier. If you are serious about saving money shipping fees are areas that you can easily make adjustments on. That said check out the nearest Decks & Docks Lumber Company which is your most reliable supplier.
