Iron cast iron railing construction standards need to keep in mind
[Cast iron railing horizontal installation process]
Wrought iron railings are equipped with standard horizontal rails according to the standard lines provided.
[Cast iron railing installation process]
(1) After the product arrives at the construction site, it shall be accurately installed in place according to the position and size specified on the drawings, and the elevation and vertical flatness shall be determined. Should be in accordance with the requirements of Party A and the design requirements of the drawings to ensure that the design requirements and acceptance criteria are met.
(2) The installation of embedded parts shall be based on the design requirements of the drawings and the actual conditions of the construction site to ensure accurate positioning so as not to cause a parallel line.
(3) Installation of wrought iron railings According to the standard lines provided, horizontal positioning and installation shall be carried out. The pre-embedded spacing shall be installed and positioned according to the site size and the design requirements of the drawings.
(4) The installation deviation must meet the national regulations and design requirements and meet the acceptance criteria.
(5) The installation of embedded parts and wrought iron railings must be firm, and the installation deviation should be in accordance with national regulations and design requirements: straightness <3mm, verticality <3mm, rail spacing error <3mm, diagonal error <3mm, vertical error of embedded parts <3mm, horizontal error <3mm.
[Cast iron railing construction precautions]
1. Before construction, carefully check whether the scaffolding, springboard, and horse stool are erected securely. The height can meet the operator's requirements. After qualification, the shelf operation can be performed. If it is found that the scaffolding does not meet the requirements, it should be rectified timely.
2. It is forbidden to wear hard-surfaced shoes, slippers, high-heeled shoes and other shelves. The number of people on the shelf must not be concentrated. The tools used must be kept safe from falling.
3. When using temporary moving lights at night construction, a safe voltage must be used to prevent electric shock and injury.
4. The construction of the basement should be done well during construction, and the watering should be fully wetted to prevent shedding, hollowing and cracks. The properties of the bonding layer and the cement bonding material should be mastered so that the layers can be firmly bonded. Pay attention to promptly sprinkle water conservation; winter use should be done to prevent frost insulation measures to ensure that the mortar from freezing, the working environment should be greater than five degrees Celsius temperature.
5. The details of construction techniques for work assignments refer to the level-by-level technical disclosures made by supervisors in charge of construction workers and construction workers.
6. In accordance with the rules to set rules, find rules to ensure that the square of the yin and yang angle, the underlying surface of the formation, after passing inspection before the tiles can be posted.
7. Where there is not enough space, based on the design and construction specifications, the ground floor must first be modeled. After confirmation by the relevant departments, large-scale construction can only be completed. Conclusion: Construction steps and precautions for cast-iron railings are for everyone. Introduced here, we have to note that although the cast iron fence has brought a lot of convenience and reality, but in the process of construction of cast iron railings, it is still necessary to abide by the relevant rules and regulations, to maintain certain common sense, to avoid a moment of negligence. The tragedy that comes with it is not worth the candle.

Basically there are two types of Diameter Tape Measure, one is Pipe OD Tape Measure Diameter Circumference, another is ID (Inner Diameter) PP Tape Measure
Pipe OD Tape Measure Diameter Circumference
Product Description:
The 2-meter Pipe OD Tape Measure Diameter Circumference is made of reliable material to satisfy precise diameter measuring requirement.The reading for the perimeter, accurate to 1 mm. The tape is double sided with circumference (measures in cm & inch) and diameter (measures in inch & inch) on the either part. Pipe od tape measure adopts fiberglass tape to deliver water and stain proof effect and to ensure that it is of good elasticity for diameter measuring. The retracting mechanism is built in the durable ABS case, thus service life is extended. Wintape provides the diameter tape measure with other patterns and offers customized logo for you.
ID (Inner Diameter) PP Tape Measure
Product Description:
Inner diameter tape measure is made of PP material that is of excellent stress tensile strength and high elasticity. The scale numbers are already been calculated so the tape gives you the result directly without calculating. The practical ID measuring tape can be adopted in various ways such as pipe and container measuring. The double sided inner diameter measuring tape makes number reading easier and more convenient.
