All steel sheet piles supplied by Hanzi are marked with a unique number and come with a manufacturing certificate. Sealed steel sheet pile partitions can be used to prevent leachate from contaminated ground or waste disposal sites from leaking beyond the site boundaries. This can present a unique engineering challenge and a challenging delivery schedule. Hanzi also has comprehensive quality control, manufacturing, and inspection and testing procedures, all of which are fully documented and available upon request.
It is important to note that concrete and slurry wall systems are porous in the long term. Since they are relatively brittle materials, their water retention capacity decreases if cracks develop due to movement or load fluctuations. This document provides certification of the raw materials used for the piles, traceability of the raw materials during production, quality inspection documentation, and independent test certificates. The O-Pile system is a rapidly growing construction method that utilizes pipes to cost-effectively construct extremely strong foundations, barriers, and retaining walls. Large piles are manufactured to the latest international standards OZ13A, OZ14A, OZ15A, OZ16A, OZ17A, and OZ18A. Sheet pile barriers offer a sealed solution with a smaller footprint, and barriers can be placed at the site boundary to maximize ground area utilization. We plan ahead. When you say 4-week delivery, we say 3.
Hanzi has designed and supplied OZ steel sheet piles for projects in New Zealand, Antarctica, Afghanistan, Australia, Chile, China, Haiti, and Kenya. Sheet piles used for basements or building perimeter foundations can also be sealed to prevent gas and leachate from brownfield redevelopment sites from entering the building. Every customer has a reason to work with us. At Mer Lion Metals, we understand your needs and will do our best to provide you with a seamless, hassle-free solution.
Hanzi currently has production facilities in Malaysia, China, and the UAE, with a combined annual production capacity of over 100,000 tons. These traditional methods require significant land, are often located far from the site edge, and are prone to leakage. O-Piles® are a stronger, more efficient, and more economical alternative to high-modulus walls using beams and heavy Z- or U-shaped sheet piles. ThyssenKrupp has distributors in most regions of the world. ESC sheet piles have been used on projects managed by leading engineering firms, including Mott MacDonald and Beca.
Traditionally, these barriers to horizontal liquid flow are constructed using clay embankments or cement-bentonite walls. OZ19A, OZ20A, OZ20, OZ21, OZ22, OZ23A, and OZ24 can also be removed and reused or recycled at a later date. In addition to high-quality products and reliable customer service, Mer Lion offers steel pipes with welded patented connectors to form continuous or modular steel walls. We partner with manufacturers of steel, coatings, tie rod systems, tape wrap systems, cathodic protection systems, and all other products typically associated with sheet pile construction to provide complete solutions for our customers.
