Ten tropical and home-grown hardwoods, five..
Stage 2: To assess the potential marine borer resistance and abrasion resistance of the candidate timbers on the long-list using a range of novel, fast track laboratory screening tests, as well as a marine exposure trial. The performance of the candidate species was compared against that of Greenheart and Ekki which
Such standardized measurements can produce two quantities: abrasion rate and normalized abrasion rate (also called abrasion resistance index). The former is the amount of mass lost per 1000 cycles of abrasion. The latter is the ratio of former with the known abrasion rate for some..
ABSTRACT In its wise use, many properties of wood are important. Among these properties, wood abrasion resistance (AR) and withdal capacity of screws (WCS) are deemed to be relatively significant. It is well know that heat treatment changes the resistance features of wooden materials by changing the structural..
Suitable for general use on furniture, door panels and frames, pelmets, skirting boards, counters, wall partitions and general woodwork. Characteristics: Manufactured from an oil modified polyurethane resin. Advantages: Retains natural beauty of the timber. Excellent adhesion to timber. Hard-wearing, abrasion resistant..
We provide a wide range of timber testing to determine whether a product demonstrates compliance with a particular standard or specification or to provide reassurance that the product will perform adequately in specific environments or end uses. Such timber testing for performance includes: Abrasion resistance; Density..

Translucent satin topcoat for use on timber decks. Based on a special oil-alkyd resin combination and selected UV-absorbing pigments. Highly transparent; ensures optimum visibility of the wood grain. Withstands physical wear. Microporous; allows the wood to breathe. Weather resistant. Water repellent. Very easy..
Mar 31, 2011 . Hardness: Resistance of the wood to indentation and its relative ease of working with hand tools. Timbers are classified into six hardness categories: 1, very hard; 2, hard; 3, moderately hard; 4, firm; 5, soft; 6, very soft. Hardwood / softwood: Regardless of weight or hardness, 'hardwoods', e.g. red cedar, are..
Key words: Hardness value, abrasion-wear resistance index, basic wood density, wood flooring. INTRODUCTION. Several mobile saw millers convert indigenous hardwoods into boards for the furniture industry. The timber is harvested from state land through concessions managed by the Forestry Commission of Zimbabwe..
So named because the fruit bears a resemblance to the fruit on hop vines, hence hop-hornbeam. Sometimes referred to as Ironwood, though it is one of the few hardwoods bearing this name that do not actually sink in water. The name is instead given for the wood's toughness and resistance to wear and abrasion
timber flooring. PRODUCT FEATURES. The Forma-lock locking system provides extremely high joint strength (tensile strength 800kg per lineal metre) allowing for . durable scratch, wear and stain resistant. The Forma-lock locking system allows quick, easy and no mess installation with no special tools or glue required
standardized concrete test was used to measure the abrasion resistance of each of the mixes. The results did not show a strong ... timber ties. If durability problems remain unresolved, concrete ties forfeit most of their advantages over timber ties and fail to deliver their full potential. There are multiple causes of concrete..
Naturally durable hardwoods are usually higher in density than softwood and their impact and abrasion resistant properties are reasons why they are used on commercial projects that have a lot of heavy use. Properly constructed decking using naturally durable species or appropriately treated low durability species can..
