most robust and reliable framework deemed the stairs, with metal frame, in turn, is the undisputed leader in these qualities.Modern metal frames can be hidden (lined with other materials), and open, creating a harmonious ensemble with other elements, as well as with the overall interior design.Using a metal ladder scaffolds allows you to create a truly unique composition, with the unimaginable twists under imaginable angles with complex barriers of different metals, with a fairly heavy spans platforms and is used for various purposes.Metal frame staircase has high durability and can withstand not only the weight of people walking on it, but the severity of the massive handrails and banisters, heavy decor and even if a particular desired piece of furniture or equipment.

Types metal skeletons
for different types of ladders used different metal frames.Depending on which ladder will be installed: the usual march, winder, spiral, curved, spiral or turning with a platform, hidden or open, select the type of frame.
Cheapest - closed frames
Initially this framework is designed so that all its components are completely hidden under the stairs and paneling, so its appearance is not subject to special requirements.Most often it is made from cheaper sills with the corners.The only thing is to be taken seriously even in this case - is a strength calculation as neglect of this point can result in serious injuries at the further operation of the stairs.
normally closed frame of metal stairs is a base substrate consisting of channels, mutually connected in several places.They fasten the corners, so-called "headscarf" serving support for steps and risers.Corners can be replaced by sheet metal, but it is significantly harder to manufacture the frame.Subsequently, the side of the stairs on a metal frame gated closed with a decorative panel of wood or drywall.
open frame with two stringers
These frames are made of a metal profile having a rectangular cross-section.Both kosoura performed in a "ladder" and covered by enamel.Now it is enough to set them on the steps and railing and stairs will complete sophisticated look.A small negative - on a metal frame ladder prices are slightly higher than in the private.In addition, when independent manufacturing welds should be carried out as carefully as possible, so they will not be seen after coating.
open frame single stringers
Usually, one frame with stringers - a single carrier beam, which are mounted under the headscarf or site level.Riser in this case are not installed.These designs look very transparent and air, but if marches are planned wide, it is recommended to weld additional side console.This will prevent the deflection stages at high loads.
Manufacturing metal frame
With minimal welding skills welded frame ladder (of course, not exclusive, and simple) can be done by hand.The technology to create multiple versions of this design.By the way, we will not discuss in detail the calculation of the stairs, but if you suddenly bit forgotten how to do it, the downstream video explains it all available.
this frame is made simple enough.We need a channel and corners.Of channel welded frame, on the side of which are welded corners.This stage can be attached to them in two ways:
- simple laying on the area, which in this case is completely under the stage;
- to the corners attached to the channel, cook a little longer two segments of the corner so that they form a frame, which will be placed and subsequently stage.
Tip: If you use instead of the channel bar shaped tube, when moving the stairs will not be felt the vibration as the tube is more rigid.
If desired, you can also step weld sheet metal.At the end of the work, all joints should be clean with a file to remove any burrs formed.Before we cover the frame with paint finished, it must be primed with a special solution to prevent rust.
for manufacturing a skeleton of a spiral staircase we definitely need a tube of sufficient length for the central column and the pipe of the same length, but a larger diameter for mounting steps.Tubes, under the stage, exactly perpendicular to cut into the sleeve length of 230-260 mm.
Important: The pipe must be cut exactly perpendicular, otherwise it will be difficult to achieve the correct angle steps.
These sleeves should sit tight as possible to the pipe, prepared by the central rack straight out and play.If you can not pick up such diameters to achieve this without the use of any tools, you can make special ring-seals of suitable diameter rod.
Tip: To get the correct size rings and bars in their manufacture should be wound on a smaller diameter pipe.
Now, these rings can be welded into the sleeve and polish their hand router.In order to obtain the same level of size, it is easier to make once for them a special jig.We need the mandrel tube and several wooden slats.Merge them, giving shape design stage.
Tip: mandrel pipe can be glued together from several pieces of chipboard.
Now you can easily and quickly cook all stages of investing in the resulting tube jig and exposing them to the desired angle.At the same time steps are welded to his sleeve.Upon completion of this work, we clean all burrs formed at the seams steps.
Now, with peace of mind you can begin to assemble the frame.For this sleeve dress neatly in the central rack and install the resulting design on prepared place.For greater strength and reliability of the bottom of the rack better concreted.
After installing the exhibit all the stages necessary for us around the corner and that they are securely fastened, weld them together in small racks.Steps should be laid on the receiving frame only after priming and painting all its surfaces.
Stairs with steps "Duck step»
If the room is possible to place only the steep stairs (slope greater than 40 °), then their level best to make a special form.Paddle-shaped stage, set in pairs in the opposite direction, to hide this shortcoming as uncomfortable walk, but can become a cause of the following disadvantages - at each stage can be put only one foot in either right or left.With this step on the ladder becomes waddling "duck."Actually, hence the name.
ladder frame will be exactly the same as for any other, but with the steps necessary to a little tricky.Best of all stages of the frame made of square tubing.Each step is made separately and then attached to the stringers.
frames can be manufactured using the drawing and raskraivaya each step individually, but it is better to spend some time on the creation of the conductor, as we have described in the paragraph on the establishment of the frame spiral staircases.As a result, it will save a lot of time and eliminate the need to carefully measure the correct angle of each stage.After making the frame all seams carefully sanded, primed with a rust inhibitor blank and painted.
course, to carry out all these activities can only be a person who owns certain skills of welding, which we will not talk in this article.Welding business has a lot of nuances and characteristics, not knowing that is very easy to spoil the whole manufactured metal frame or inflict damage that can later lead to structural failure.That is why, if you do not have enough experience, do not even try to make a metal frame ladder on their own.The more that a huge number of manufacturers offer prefabricated metal frames, and many companies quickly and at an affordable price will make the design of any complexity.
