How to Choose the Right Scaffolding Manufacturer?
There are many scaffolding manufacturers all over the world. Some manufacturers may offer you cheap prices and simple erecting structures. While others may offer you the best quality you need. When you’re looking for a scaffolding manufacturer, there is something you should bear in mind. There are many factors you may face when choosing the right scaffolding manufacturer for your construction project including Communication, Price, Qualifications, and Location of Factory.

Formwork Types and Its Application In Construction
Construction formwork, also known as shuttering, is a permanent or semi-permanent structure used to support the construction building being erected. The formwork consists of concrete that is poured and hardened to withstand all types of loads. It should be properly braced both vertically, and diagonally so that it keeps its form and structure. It should be set accurately, be as light as possible with waterproof joins so that no swelling or movement occurs.

Four Different Types of Stainless Steel
#1 Ferritic Stainless Steel Based on Chromium with small quantities of Carbon, ferritic stainless steel has a similar microstructure to both carbon and low alloy steels. Compared to other types of stainless steel, it is usually limited to the use of relatively thin sections, due to a lack of toughness in welds. Although, contractors use ferritic stainless steel for a wide range of applications that do not require welding. Additionally, you cannot harden ferritic steel with heat treatment. But you can use it in seawater or other aggressive conditions when you include the addition of Molybdenum. Ferritic stainless steel is also magnetic, but not as formable as austenitic stainless steel for example. On the other hand, steelworkers often choose ferritic stainless steel because of its resistance to stress corrosion cracking.

The Difference Between 304 & 316 Stainless Steel
When selecting stainless steel that must endure corrosive environments, austenitic stainless steel is typically used. Possessing excellent mechanical properties, the high amounts of nickel and chromium in austenitic stainless steels also provide outstanding corrosion resistance. Additionally, many austenitic stainless steels are weldable and formable. Two of the more commonly used grades of austenitic stainless steel are grades 304 and 316. To help you determine which grade is right for your project, this passage will examine the difference between 304 and 316 stainless steel.

Do You Know What is Mechanical Rebar Splice?
A mechanical rebar splice is a joint or a coupler used to splice two rebars. The mechanical rebar splicing is a new type of splicing in the world construction industry. The mechanical rebar splice has many advantages compared to the conventional method of overlapping. A longer reinforcement bar is obtained through this rebar coupler splicing. The errors due to wrong lap length as in the conventional method are avoided. The wastage of steel is reduced. The use of a mechanical rebar joint helps to avoid lap length. This will save the appreciable amount of steel. We can use couplers as dowel bars. This will save the formwork material.

What’s the Importance of Using Lap Rebar Splices?
The lap rebar splice is the most common and economic rebar splice used in the construction project. Compared to lap rebar splicing, the welded rebar splices and mechanical rebar splices require more labor and skill.

Introduction of Tension and Compression Mechanical Splices for Rebars
This type of mechanical rebar splice can resist tension and compression stress. There are sizable numbers of commercially manufactured tension and compression mechanical splices for rebars. Tension and compression mechanical rebar splices types, designated bar sizes to be spliced by each splice type, the grade of the steel bar which is spliced using certain types of tension and compression mechanical rebar splice, and installation condition of each mechanical rebar splices are provided.

What Are the Methods of Splicing Reinforced Bars?
Most of the reinforced concrete structures won’t be provided with full-length rebars. The manufacture and transportation of long bars are difficult, which limits the use of full length reinforced bars. The method used to join the reinforcement bars, so that the force is transferred effectively from one rebar to the other rebar is called as rebar mechanical splicing. The integrity of the concrete structure is dependent on the proper mechanical splicing of the reinforcement bars.

Operations in Rebaring for Reinforced Concrete Works
The three main operations carried out in rebar for reinforced concrete construction bars are cutting, bending and tying. The diameter of reinforcement bars used reinforced concrete work mainly ranges from 6 to 42mm. These reinforcement bars come from the steel mill in specified lengths.

Equipment Used for Rebar Techniques
The usage of chisel and hammer was an earlier practice used for rebar bending. The rebar is held fixed with the help of three thick rebars over a rebar bender bench. Then the bending is done by means of manual force, operated with the help of levers. To tie the rods, cutting pliers were used, and tied by steel wires.

Safety Issues During Scaffolding Works
Improper scaffolding works will result in hazards. Fall hazards have occurred if the scaffolds are not properly erected or used. Every scaffolding must be erected with strong foot bearing plates to avoid collapse. Following the safety practices during scaffolding works can help to prevent injuries and fatalities.

What are the Types of Mechanical Splices for Rebars?
Mechanical rebar splices for rebars in concrete construction is an effective method of joining reinforcing bars. These are designed based on codes of standard practice. Mechanical splices in reinforced-concrete construction should meet the building code requirements for developing tension and compression as required

Equipment Used for Cutting of Reinforcement Bars
#1 Electric Rebar Cutters Electrical cutters that can cut diameters up to 16mm are employed. These consume power to cut the bars. Higher varieties are available in the market. #2 Heavy-Duty Rebar Cutter These are a higher version of the same, the heavy-duty cutters, that have the capability to cut the bars up to 42mm. At a time, these cutters can cut three to six bars at a time. These cutters make use of oil bath lubrication, which makes the operation noiseless. The system is simple and hence easy to use.

Rebaring Equipment Used for Tying Rebars
The equipment that is used for rebaring operations is developed with time, as the size of bars is increasing. Larger size bars are difficult to be handled by hand operation. For rebar machines, there are not only rebar thread rolling machines and rebar cutting machines, but also the rebar tying machines. For rebar tying machines, we supply both manual machines and automatic machines.

Necessity of Rebar Connection System in Reinforced Concrete Construction
The steel reinforcement mostly is divided into two categories i.e. #1 Primary reinforcement or main steel reinforcement #2 Secondary reinforcement or distribution reinforcement Main steel reinforcement bars are employed in R.C.C structures to ensure resistance against the whole design loads coming over it. The secondary reinforcement bars are mainly employed due to durability as well as for aesthetic reasons.
