Q:The steel structure of 40*80 steel, it is tempered glass top. The steel internal fight foaming agent. But there is rust in the inner surface. Will it affect the safety? How to deal with
Generally it is installed, both ends of the welding pipe will be closed, if the internal tube can be in a closed state, the inner wall surface after a certain period of time, will form a passivation layer, no further corrosion, so long as the section strength enough, in the period of use should be safe.
Q:The steel and wood preservative in the flower is how to connect
A dovetail screw / stainless steel fixed special anticorrosive wood keel screws,
Q:Glass partition, square box outsourcing 1mm thick stainless steel, glass middle is how to set the quota
Can consider to increase the insurance factor, the edge of the glass with epoxy resin and solid wall such as granite wall adhesion (which went to the production of glass curtain wall) will not allow the use of styrofoam! Because of adhesive power, shear resistance and so on are poor.
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
You can't weld well without using tools, and it can't be welded with high quality. If the site is large and batch welded, you can use wood as a standard corner frame (quite a template). ), if the amount is small, you can buy a wooden triangle plate, steel square to live, post welding,
Q:100*100*2.5 square with 20 square meters of housing security light steel structure:
The span of the main girder in the sunlight room is 20 square meters, but the different shapes lead to the different span of the main beam.
Q:The joiner board is fixed on the square on how
With self tapping screws, that is, with drill screws, building materials market can buy. Electric screwdriver, you can put the wood board through self tapping screws into the steel. But attention should be paid to buy the self tapping screw length, short patch does not live too long into the square, too much is not good.
Q:What is the hot dip galvanized steel, production process?
Also called hot galvanized and hot dip galvanizing: hot dip galvanizing is an effective way of metal corrosion, mainly used for metal structure on the facilities of the industry.
Q:How much is the thick wall hollow square 30*30
Hollow square 30*30 wall thickness is 5mm.
Q:Square steel and C steel which is better?
Then use the square. Beautiful C steel, general color steel is not used. See you square high-rise, is firmly with the 100 by 100.
Q:It can be used as the steel electrical equipment grounding
The steel can be used as grounding of electrical equipment, but because of the steel and the earth contact surface is relatively small, the grounding efficiency is not high, generally do not use. The steel pipe, angle steel and flat steel and other materials, the ratio of the circumference and area, has a larger contact area with the earth, in the same material case, get smaller grounding resistance, or in the same requirements of the grounding resistance, supplies are more economical than small, square steel.
