Yixing Hualong New Material Lumber Co., Ltd.

1.WPC is mainly used in outdoor
2.Cut and Borehole
    (1)Suppose using alloy sawblade and drills
    Tips: Using few teeth blades (eg, 45cm length, 18-24 teeth) will be easier.
    (2)Hualong products are different from wood with very convenient using, you don't have to consider the grain and crunode.
    (3)While drilling big or deep holes, you should pull out drills regularly in order to take out scraps, do not intend to bore holes at once.
3.Transportation and storage
    (1)WPC product has bigger weight and lower elasticity than wood, you have to be more careful when using it. When put up a Hualong product with the same vol. as wood, you will have to make more efforts and care for snap.
    (2)Storage in building site, you should put the products on the flat floor.
    (3)It should stack the products from both sides of the joist, the space between two joists should be equal or less than 60cm, and the joists should be arranged vertically with the profiles.
    (4)Deposited the WPC in outdoors should package completely and stack in level up, avoid insolation and distortion.
    (5)Because of the WPC friction coefficient is less than hardwood floor, when transit you should not put on the WPC, in order to avoid destroying the floor surface.
4.Installation
    (1)In the base case, joists need 30 to 50cm intervals when install Hualong WPC (according to the size of products).
    (2)Tapping screw wears well, the first choice of installing Hualong WPC.
    (3)You have to bore holes in advance before installation, and the holes' diameter should be less than three quarters of nail and bolt.
    (4)When the width is greater than 10mm, each end should use two bolts to fix.
    In some particular environment or super-normal loading conditions (eg, bathhouses), the interstice should be shorter.
5.Gap
    Because of drainage, sweep, slight heat expansion, and contraction, etc. there should be some proper interstice among the edges and the ends.
    Edge>=4mm
    The interstice among the ends are up to the length of the products, the coefficient of heat expansion (), and the local highest temperature.
    Numeration of the interval among the ends
    The length of the product: L meter, the highest temperature of local place in one year: Tmax, the temperature when installation: T, here the formula is .
    For example, a 2 meters long product, and the temperature when installation is 10, the highest temperature in one year is 40. 
    So the interstice among the ends when install this kind of product is:

    Notes: when install Hualong WPC products, there must be some proper interstice, and fix the products directly on the joist. Don't fix the products directly on any solid surface, such as concrete, roof board, and so on.
    (1)Hualong WPC, when used as balustrade, should be lined with steel tube or square steel, also firmly with the terrace, every 450mm interstice need to be lined to keep from distortion and falling.
    (2)When used as arbor or flowerpot, you must take coefficient of heat expansion into consideration, and line with square tube between upright post and transom, also link firmly in vertical.
    (3)Hualong WPC material has some definite plastic characteristic, so when the length is longer than 3m, the product will have a little bend, it will be proofreaded normally.
    (4)When install the products uprightly, and the length is longer than 3m, each end should be fixed up with 4 snails, and the vertical interstice should longer than 40cm in order to stress averagely for 4 snails.
6.The selectivity of UV-531, if the clients demand, the color fading will be 20% more or less, if do not use, it will be 60% more or less. It's up to you.
7.Rinse
    (1)The pollution of tools, mildew, berry and defoliation: using detergent with sodium hypochlorite.
    (2)Remove rust and dust: using abluent with phosphoric acid.
    (3)Remove oil and grease, etc. with a suitable detergent or degreaser
    (4)Clear the litter in interstice with tools regularly and assure the drainage is freely.
    Tips: Burnish grease on WPC using a fine emery paper. The place burnished will look like a new one, and also the color will changed a little influenced by the weather.
